EN 10028-5 P355ML1 Steel Plate | P355ML1 TMCP -40°C Vessel Plate

P355ML1 is the −40 °C TMCP quality in the P355 family of EN 10028-5. Buyers search EN 10028-5 P355ML1, P355ML1 steel plate, 1.8832, P355ML1 TMCP -40°C vessel plate and P355ML1 supplier. ML1 is the low-temperature letter set on a thermomechanically rolled route. This page is not P355M. M is room-temperature TMCP. This page is not P355ML2. ML2 is −50 °C. This page is not P355NL1. P355NL1 is EN 10028-3 normalized plate. This page is not S355ML. S355ML is EN 10025-4 structural steel.

Yield is 355 MPa at ≤16 mm. Tensile is 450–610 MPa. Steel number is 1.8832. 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 P355M, we will not ship P355ML1 and call 355 enough. If a drawing says P355NL1, we will not ship P355ML1 and call −40 °C automatic dual name unless both books are met. Dual marking with 16MnDR 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 −40 °C comparisons belong on GB/T 713.3. Normalized fine-grain sisters belong on EN 10028-3. Structural TMCP belongs on EN 10025-4.

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

Cast Analysis and Product Analysis — EN 10028-5 P355ML1 (1.8832)

Phosphorus and sulfur sit tighter than on P355M because ML1 is a toughness quality. Carbon stays low because TMCP plus −40 °C is the job. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search P355ML1 mechanical properties, P355ML1 impact and P355ML1 -40°C. Yield still falls with thickness. Impact is the ML1 item.

Tensile and Yield — EN 10028-5 P355ML1

Elongation is typically 22% 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Do not quote 355 MPa yield on an 80 mm plate. Do not treat −40 °C as permission to stamp 16MnDR steel plate or P355NL1 without checking both books.

Buyers pick P355ML1 when a PED file wants 355 MPa TMCP plate and Charpy at −40 °C. Search phrases such as P355ML1 -40°C, P355ML1 TMCP and 1.8832 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 or SA-662 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.

P355ML1 is killed TMCP fine-grain C-Mn vessel plate. 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. A procedure written for SA516 Grade 70 without an impact extra is not automatically valid. A nickel procedure written for SA203 Grade D is the wrong family. 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.

Usual delivery from SHH STEEL is thermomechanically rolled EN 10028-5 P355ML1 (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 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 P355ML1; 1.8832; 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.

Usual supply range from SHH STEEL for P355ML1 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 plate belongs on EN 10028-3 P355NL1. Structural TMCP belongs on EN 10025-4.

Dimensional limits follow EN 10028-1 and EN 10029 unless the order names another table. Class A is the usual default. If the calculation used minimum thickness after corrosion, write the allowed minus. Do not apply ASTM A36 structural tolerances to a PED −40 °C TMCP plate without writing them. When dual-named against SA841 Grade A Class 1, write which thickness table governs.

Charpy details. Write −40 °C, joules, location and orientation. Do not write “impact as per EN 10028-5” and expect ML2.

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

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

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

Third-party. EN 10204 3.2 when written.

P355ML1 is the plate for a 355 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 P355ML2.

Experience on this grade is simple: keep the letters after P355. 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 P355ML1 from first-line mills, reports 1.8832 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. P355ML1 is not P355M. P355ML1 is not P355ML2. P355ML1 is not P355NL1. P355ML1 is not Q345R steel plate. If the drawing says −50 °C, we will not ship ML1 and call minus forty close.

EN 10028-5 P355ML1 Steel Plate is European TMCP fine-grain −40 °C pressure-vessel plate, steel number 1.8832, at the 355 MPa yield step and 450–610 MPa tensile at ≤16 mm. Whether the inquiry says EN 10028-5 P355ML1, 1.8832 or P355ML1 TMCP -40°C Vessel Plate, SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) supplies plate with P355ML1 chemistry, recorded TMCP, Charpy at −40 °C when ordered, and EN 10204 3.1 or 3.2 certification.
