Conclusion

What is EN 10028-5 P460ML1 Steel ?

P460ML1 is the −40 °C TMCP quality in the P460 family of EN 10028-5. Buyers search EN 10028-5 P460ML1, P460ML1 steel plate, 1.8837, P460ML1 TMCP -40°C vessel plate and P460ML1 supplier. ML1 is the low-temperature letter set on a thermomechanically rolled route. This page is not P460M. M is room-temperature TMCP. This page is not P460ML2. ML2 is −50 °C. This page is not P460NL1. P460NL1 is EN 10028-3 normalized plate. This page is not P420ML1. P420ML1 is a 420 MPa step. This page is not S460ML. S460ML is EN 10025-4 structural steel.

Yield is 460 MPa at ≤16 mm. Tensile is 570–720 MPa. Steel number is 1.8837. Delivery is TMCP (M). Charpy is specified at −40 °C when the order follows ML1. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). We buy this grade from qualified Chinese mills, check the certificate against EN 10028-5, and ship it to fabricators in the USA, Europe, Middle East, Southeast Asia, Africa and South America.

If a drawing says P460M, we will not ship P460ML1 and call 460 enough. If a drawing says P460NL1, we will not ship P460ML1 and call −40 °C automatic dual name unless both books are met. Dual marking with Q460DR steel plate is possible only when chemistry, tensile, impact temperature and delivery all fit.

This plate sits in pressure vessel steel plates and carbon steel plates. Chinese low-temperature 460 comparisons belong on GB/T 713.3. Normalized fine-grain sisters belong on EN 10028-3. Structural TMCP belongs on EN 10025-4.

Chemical Composition

Cast analysis follows EN 10028-5. Product analysis follows EN 10028-1 when ordered.

Phosphorus and sulfur sit tighter than on P460M because ML1 is a toughness quality. 460 MPa still comes from TMCP plus micro-alloying, not from extra carbon. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Mechanical Properties

Buyers search P460ML1 mechanical properties, P460ML1 impact and P460ML1 -40°C. Yield still falls with thickness. Impact is the ML1 item.

Tensile and Yield — EN 10028-5 P460ML1

Elongation is typically 17% min on thinner plate. Charpy for ML1 is −40 °C. Energy is commonly 27 J average when the order follows the book. Location and orientation must be written. Do not assume ML2 −50 °C on this page.

Do not quote 460 MPa yield on an 80 mm plate. Do not treat −40 °C as permission to stamp Q460DR steel plate or P460NL1 without checking both books.

TMCP -40°C 460 MPa Pressure-Vessel Service

Buyers pick P460ML1 when a PED file wants 460 MPa TMCP plate and Charpy at −40 °C. Search phrases such as P460ML1 -40°C, P460ML1 TMCP and 1.8837 steel plate all point here.

It is not a substitute for 09MnNiDR steel plate. That grade is −70 °C. It is not a substitute for 08Ni3DR steel plate. That grade is 3.5Ni. An ASME file should name SA-841 with a written −40 °C extra. Dual marking is possible only when both books are met.

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

Weldability

P460ML1 is killed TMCP fine-grain C-Mn vessel plate at 570–720 MPa tensile. Treat welding as production welding, and as PED / ASME Code welding when the equipment is a vessel.

Qualify to the applicable code. Consumables must keep toughness at −40 °C and match the 460 MPa band. A P420ML1 procedure is the previous family. A carbon procedure written for SA516 Grade 70 may be light on strength. Heat input on TMCP plate should stay controlled so the rolled grain is not coarsened in the HAZ. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Heat Treatment and Delivery Condition

Usual delivery from SHH STEEL is thermomechanically rolled EN 10028-5 P460ML1 (M). This is not +N from EN 10028-3.

If the vessel will see PWHT, say so. Impact after simulated PWHT is worth naming on a −40 °C 460 MPa TMCP file. Extra simulation, 3.2 hold points or special NDE add time. Plan about two months when those extras are on the order.

The certificate lists EN 10028-5 P460ML1; 1.8837; heat number; cast analysis; product analysis when ordered; tensile to the correct thickness column; M / TMCP; Charpy at −40 °C when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Dimensions

Usual supply range from SHH STEEL for P460ML1 TMCP -40°C vessel plate:

  • Thickness: commonly 6 mm – 80 mm, thicker by mill agreement
  • Width: 1500 mm – 4000 mm
  • Length: 3000 mm – 12000 mm

Normalized −40 °C 460 plate belongs on EN 10028-3 P460NL1. Structural TMCP belongs on EN 10025-4.

Tolerances

Dimensional limits for EN 10028-5 P460ML1 follow EN 10028-1 and EN 10029 unless the purchase order names another table. Class A is the usual mill default for P460ML1 TMCP -40°C vessel plate. Class B, Class C or Class D is supplied only when written. Do not apply ASTM A36 structural tolerances to a PED −40 °C TMCP plate without writing them. When dual-named against SA841 Grade C Class 1, write whether EN 10029 or SA-20 governs the minus on thickness.

Typical thickness tolerance idea for P460ML1 (EN 10029 Class A, reference)

Nominal thickness (mm)Class A minus (mm)Class A plus (mm)
6 – 8−0.4+0.8
8 – 15−0.5+0.9
15 – 25−0.6+1.0
25 – 40−0.7+1.1
40 – 80−0.8+1.2

Width on 1500–4000 mm plate is commonly held to about ±20–25 mm unless the mill quote names a tighter extra. Length on 3000–12000 mm plate is commonly held to about +50 / 0 mm or ±25 mm by mill practice. Flatness follows EN 10029 Class N unless Class S is written. Edge condition is mill edge or cut edge as ordered. If the vessel calculation used minimum thickness after corrosion, write the allowed minus on the RFQ. SHH STEEL will not assume Class B or a zero-minus extra on P460ML1 unless the order says so.

Supplementary Requirements

Charpy details. Write −40 °C, joules, location and orientation.

Impact after simulated PWHT. When the vessel will be stress-relieved.

Product analysis. Especially P, S, Al, N, Nb and V.

NDE. EN 10160 or ASTM A435 / A578 as named.

Third-party. EN 10204 3.2 when written.

P460ML1 is the plate for a 460 MPa PED file that wants TMCP and −40 °C. It is the wrong plate for LNG inner tanks. That work belongs on 06Ni9DR steel plate. It is the wrong plate for −50 °C. That work is P460ML2.

P460ML1 Supply Capability

Why Choose SHH STEEL

Experience on this grade is simple: keep the letters after P460. M, ML1 and ML2 are three different purchase orders. SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) prices P460ML1 from first-line mills, reports 1.8837 chemistry, records TMCP, prints Charpy at −40 °C when ordered, and issues 3.1 as standard or 3.2 when specified.

We keep the grade on the order. P460ML1 is not P460M. P460ML1 is not P460ML2. P460ML1 is not P420ML1. P460ML1 is not Q345R steel plate. If the drawing says −50 °C, we will not ship ML1 and call minus forty close.
