EN 10028-6 P500QL2 Steel Plate | P500QL2 QT -60°C Vessel Plate supplier

P500QL2 is the −60 °C quenched-and-tempered quality in the P500 family of EN 10028-6. Buyers search EN 10028-6 P500QL2, P500QL2 steel plate, 1.8876, P500QL2 QT -60°C vessel plate and P500QL2 supplier. QL2 is colder than QL1. This page is not P500Q. Q is room-temperature QT. This page is not P500QH. QH is elevated-temperature QT. This page is not P500QL1. QL1 is −40 °C. This page is not P460QL2. P460QL2 is a 460 MPa step. This page is not S500QL1. S500QL1 is EN 10025-6 structural QT steel.

Yield is 500 MPa at ≤50 mm. Tensile is 590–770 MPa. Steel number is 1.8876. Delivery is QT (Q). Charpy is specified at −60 °C when the order follows QL2. 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 10028-6, and ship it to fabricators in the USA, Europe, Middle East, Southeast Asia, Africa and South America.

If a drawing says P500QL1, we will not ship P500QL2 and call colder automatically better without the buyer writing the name. If a drawing says −60 °C, we will not ship QL1 and call minus forty close. Dual marking with SA517 Grade Q is possible only when both books are fully met.

This plate sits in pressure vessel steel plates and high-strength low-alloy plates. Structural QT belongs on EN 10025-6. ASME QT vessel comparisons belong on ASME SA517.

Cast analysis follows EN 10028-6. Product analysis follows EN 10028-1 when ordered.

Phosphorus and sulfur stay tight because QL2 is a colder toughness quality than P500Q. 500 MPa still comes from quench and temper 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.

Buyers search P500QL2 mechanical properties, P500QL2 impact and P500QL2 -60°C. Yield still falls with thickness. Impact is the QL2 item.

Tensile and Yield — EN 10028-6 P500QL2

Elongation is typically 16% min on thinner plate. Charpy for QL2 is −60 °C. Energy is commonly 27 J average when the order follows the book. Location and orientation must be written. Do not assume QL1 −40 °C is enough for a QL2 drawing.

Do not quote 500 MPa yield on a 120 mm plate. Do not treat −60 °C as permission to stamp SA517 Grade Q or S500QL1 without checking both books.

Buyers pick P500QL2 when a PED file wants 500 MPa QT plate and Charpy at −60 °C. Search phrases such as P500QL2 -60°C, P500QL2 QT and 1.8876 steel plate all point here.

It is not a substitute for 09MnNiDR steel plate. That grade is −70 °C nickel steel. It is not a substitute for 08Ni3DR steel plate. That grade is 3.5Ni. It is not LNG inner-tank plate. That work belongs on 06Ni9DR steel plate. An ASME QT file should name SA-517 with a written −60 °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.

P500QL2 is killed QT fine-grain C-Mn vessel plate at 590–770 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 −60 °C, not only at −40 °C. A P500QL1 procedure is the previous family. A carbon procedure written for SA516 Grade 70 is light on strength. Preheat and interpass must stay inside the qualified window so the QT structure is not damaged. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL is quenched and tempered EN 10028-6 P500QL2 (Q). This is not +N from EN 10028-3 and not M from EN 10028-5.

If the vessel will see PWHT, say so. Impact after simulated PWHT is worth naming on a −60 °C 500 MPa QT 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 10028-6 P500QL2; 1.8876; heat number; cast analysis; product analysis when ordered; tensile to the correct thickness column; Q / QT; Charpy at −60 °C when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for P500QL2 QT -60°C vessel plate:

• Thickness: commonly 8 mm – 150 mm, thicker by mill agreement
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm

Structural −60 °C 500 QT plate belongs on EN 10025-6. ASME QT vessel plate belongs on SA517 Grade Q.

Dimensional limits for EN 10028-6 P500QL2 follow EN 10028-1 and EN 10029 unless the purchase order names another table. Class A is the usual mill default for P500QL2 QT -60°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 −60 °C QT plate without writing them.

Typical thickness tolerance idea for P500QL2 (EN 10029 Class A, reference)

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 P500QL2 unless the order says so.

EN 10028-6 P500QL2 is already a −60 °C QT quality. Extra items still have to be written on the purchase order. SHH STEEL will not assume them from the grade name alone.

Charpy details. Write −60 °C, joules, specimen size, location and orientation. Transverse and longitudinal are not the same test. Do not write “impact as per EN 10028-6” and expect the mill to guess QL2.

Impact after simulated PWHT. When the vessel will be stress-relieved, name the hold temperature, hold time and cooling rate used on the test coupon. A 500 MPa QT plate can lose toughness after a long PWHT cycle. The coupon should see the same cycle the vessel will see.

Product analysis. Especially P, S, Al, N, Nb, V, Ni and Mo on finished plate. Cast analysis alone is not always enough for a destination file that wants product analysis.

Through-thickness / Z-test. Name Z15, Z25 or Z35 when the plate will be welded in the thickness direction or used for nozzles and tees. Reduction of area must sit on the certificate.

NDE. EN 10160 class, ASTM A435 or ASTM A578 as named. Write scanning extent and acceptance class. For thick QT plate, UT after quench and temper is the usual route.

Hardness. If the destination file caps hardness after QT or after simulated PWHT, write the max HB or HV and the test location.

HIC / SSC / NACE. Only when the equipment is sour service. P500QL2 is not automatically NACE MR0175 / ISO 15156. Write the test method, solution and acceptance if required.

Third-party witness. EN 10204 3.2 with SGS, TÜV, BV, ABS, CCS, DNV or the inspector named. Hold points for heat treatment, tensile, −60 °C impact and UT should be listed on the ITP.

Identification and stamping. Heat number, grade P500QL2 / 1.8876, QT, thickness and mill logo on each plate. Transfer marks after cutting if the plate will be cut before shipment.

P500QL2 is the plate for a 500 MPa PED file that wants QT and −60 °C. It is the wrong plate for LNG inner tanks. That work belongs on 06Ni9DR steel plate. It is the wrong plate for −40 °C only. That work is P500QL1.

SHH STEEL sources EN 10028-6 P500QL2 from first-line Chinese mills and ships it on worldwide terms. Partner mills include Wuyang (Wugang), Angang, Shougang, Hanye, Anyang Iron & Steel, Baosteel, Xinyu, Xingcheng, Yongjin, Tsingshan, TISCO (Taiyuan), Jiuquan (JISCO), Lianzhong, Zhangpu and Baoxin, plus other qualified mills when the size or QT route requires it.

Mill test certificates are issued to EN 10204 3.1 as standard. EN 10204 3.2 is arranged when the order names a third-party hold point.

Experience on this grade is simple: keep the letters after P500. Q, QH, QL1 and QL2 are four different purchase orders. SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) prices P500QL2 from first-line mills, reports 1.8876 chemistry, records QT, prints Charpy at −60 °C when ordered, and issues 3.1 as standard or 3.2 when specified.

We keep the grade on the order. P500QL2 is not P500Q. P500QL2 is not P500QL1. P500QL2 is not S500QL1. P500QL2 is not Q345R steel plate. If the drawing says −40 °C, we will not ship QL2 and call colder automatically better without the buyer writing the name.
