ASME SA36 Steel Plate | SA-36 Carbon Structural Plate Supplier

ASME SA36, also searched as SA-36, SA36, SA36M, ASME SA-36/SA-36M, SA-36 plate and ASTM A36, is carbon structural steel adopted into ASME Boiler and Pressure Vessel Code Section II, Part A. The current Code text states that SA-36/SA-36M is identical with ASTM A36/A36M for the ASTM edition listed in that Code year. Chemistry, tensile, yield and elongation are the same numbers. The difference is the name on the purchase order and the name printed on the mill test certificate.

This book covers carbon steel plates, shapes and bars of structural quality for riveted, bolted or welded construction of bridges and buildings, and for general structural purposes. It is not a pressure-vessel plate book. It is not ASTM A516 Grade 70. A516 / SA-516 sits under A20 / SA-20. It is not ASTM A573 Grade 58 / 65 / 70. A573 is a toughness tank plate limited to 40 mm. It is not A572 Gr.50. A572 is Nb-V HSLA.

Tensile is 58–80 ksi / 400–550 MPa. Yield is 36 ksi / 250 MPa min for the usual plate thickness band. Plates over 8 in [200 mm] may drop to 32 ksi / 220 MPa yield under the A36 / SA-36 table. Elongation on plates and bars is 20% in 8 in and 23% in 2 in. General requirements follow ASTM A6 / ASME SA-6, not A20 / SA-20.

SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). We buy SA-36 / A36 from qualified Chinese mills, check the certificate against the name the order actually wrote, and ship plate to fabricators in the USA, Europe, Middle East, Southeast Asia, Africa and South America. If the drawing says SA-36, the MTC says SA-36. If the drawing says A36, the MTC says A36. Dual marking is possible only when both books and the Code edition table are met.

HSLA sisters belong on ASTM A572 / A572M structural steel plates. European structural sisters belong on EN 10025-2. Vessel carbon sisters belong on ASTM A516 and ASME SA516.

SA-36 uses the same chemistry table as A36. Carbon and manganese change with thickness. Product analysis, when ordered, follows A6 / SA-6 product-analysis tolerances.

Heat Analysis — ASME SA-36 / ASTM A36 Plates

Thin plate does not carry a manganese range in the A36 / SA-36 table. That is normal. Do not reject a 12 mm SA-36 plate because Mn is not 0.80–1.20. Silicon is required on plates 40 mm and over in many editions; write it if the destination file cares. Copper is only a minimum when the order specifies copper steel.

This chemistry is not ASTM A283 Grade C. It is not A572 Gr.50. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search SA36 mechanical properties, SA-36 yield, ASME SA36 tensile and A36 vs SA36 strength.

Tensile and Yield — ASME SA-36 / ASTM A36 Plates and Bars

Shapes use the same tensile and yield, with 21% elongation in 2 in. For plates wider than 24 in [600 mm], A6 / SA-6 reduces elongation by two percentage points. Floor plate need not report elongation.

Do not quote A573 Grade 70 (485–620 MPa, 290 MPa yield) on an SA-36 order. Do not quote ASTM A516 Grade 70 (485–620 MPa vessel table) as if it were SA-36.

SA-36 and A36 are the same chemistry and the same tensile table. They are not automatic substitutes for every other 250 MPa structural plate in the world.

In the United States the two official names are ASME SA-36/SA-36M and ASTM A36/A36M. ASTM A36 steel plate is the everyday structural search. SA-36 is the Code / Section II search. ASTM A283 Grade C is a different carbon plate book. A572 Gr.50 is HSLA.

In Europe buyers compare EN 10025-2 S235JR, EN 10025-2 S235J0 and EN 10025-2 S275JR. S235 is closer on yield. S275 is stronger. See EN 10025-2.

In Germany the usual comparison is DIN 17100 St37-2 or DIN 17100 St37-3. See DIN 17100.

In Japan they compare JIS G3106 SM400A, JIS G3106 SM400B or JIS G3106 SM400C. See JIS G3106.

In China the nearest carbon structural comparison is GB/T 700 Q235 (Q235B / Q235C / Q235D) and GB/T 3274 Q235 plate. Q345 lines up with A572 / S355, not SA-36.

Dual marking is possible only when both books are fully met.

Buyers pick SA-36 when a bill of materials, a Code list or an EPC specification writes the ASME name. Buyers pick ASTM A36 steel plate when the job is a warehouse, a platform, a base plate or a general structure. Search phrases such as SA36, SA-36, SA36M, ASME SA36 plate and SA-36/SA-36M all point here.

It is the wrong plate for a Section VIII vessel that names SA-516. That work is ASTM A516 Grade 70 and the ASTM A516 family. It is the wrong plate for HSLA frames that name A572 Gr.50 or ASTM A572 Grade 65.

SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia.

SA-36 is ordinary carbon structural plate. It welds with the processes used on A36: SMAW, GMAW, FCAW, SAW and oxy-fuel where the shop still uses it.

Qualify to the applicable structural code or, when the equipment is Code work that actually listed SA-36, to Section IX. Consumables are carbon-steel family electrodes. A procedure written for EN 10025-2 S235JR is close in alloy type but is not automatically the SA-36 WPS. A procedure written for ASTM A516 Grade 70 is a vessel procedure. Preheat on thin plate is often not required; thick plate and low ambient temperature still need a written WPS. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL for SA-36 plate is as-rolled. Normalized plate is supplied when the purchase order asks for it. SA-36 does not require quench and temper. It is not a Cr-Mo vessel heat-treatment book.

If the structural specification asks for Charpy, write the temperature and joules. A36 / SA-36 does not automatically include impact. If the job wants copper-bearing plate, write Cu min 0.20.

The certificate lists ASME SA-36 / SA-36M and/or ASTM A36/A36M as the order named; heat number; heat analysis; tensile to the 400–550 MPa table; delivery condition. Certificates may be EN 10204 3.1 or EN 10204 3.2. When the contract cites a Code year, SHH STEEL checks that the ASTM edition on the MTC is acceptable to that Code year’s Table II-200-1.

Usual supply range from SHH STEEL for SA-36 carbon structural plate:

• Thickness: 6 mm – 200 mm, thicker by mill agreement under A6 / SA-6
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm

This is not limited to 40 mm. That 40 mm cap belongs to A573, not SA-36. Shapes and bars are in the same book but are quoted as separate items. Browse more sizes on the products index.

Dimensional limits for ASME SA-36 plate follow ASTM A6 / ASME SA-6 unless the purchase order names another table. Do not apply pressure-vessel A20 / SA-20 extras unless the order writes them.

Typical thickness tolerance idea for SA-36 plate (A6 / SA-6 reference)

Width on 1500–4000 mm plate is commonly held to about ±20–25 mm unless a tighter extra is named. Length on 3000–12000 mm plate is commonly held to about +50 / 0 mm or ±25 mm by mill practice. Flatness follows A6 / SA-6 unless a tighter class is written. Edge condition is mill edge or cut edge as ordered. Camber and out-of-square follow A6. If the calculation used minimum thickness after corrosion or after machining, write the allowed minus on the RFQ. SHH STEEL will not assume a zero-minus extra on SA36 plate unless the order says so.

SA-36 already defines chemistry and the 400–550 MPa tensile table. Extra items still have to be written on the purchase order.

Name on the certificate. Write SA-36, A36, or both. Do not leave it to the mill to guess.

Code year. If the job is tied to a BPVC edition, name that year so the ASTM revision on the MTC can be checked.

Charpy details. Write temperature, joules, location and orientation if impact is required.

Normalized delivery. Write it when the file wants N instead of as-rolled.

Copper steel. Write Cu min 0.20 when atmospheric corrosion is a concern.

Product analysis. Especially C, Mn, P and S.

Through-thickness / Z-test. Name Z15, Z25 or Z35 when the plate will be welded in the thickness direction.

NDE. A6 ultrasonic extras as named.

Identification and stamping. Heat number, SA-36 or A36, thickness and mill logo.

Third-party witness. EN 10204 3.2 with SGS, TÜV, BV, ABS, CCS, DNV or the inspector named.

SA-36 is the plate for a file that wants carbon structural plate under the ASME name. It is the wrong plate for a pressure vessel that names SA-516. That work sits on pressure vessel steel plates. It is the wrong plate for weathering design that names Corten. That work sits on Corten A / B.
