JIS G3115 SPV490 Steel Plate | SPV490 QT Vessel Plate

SPV490 is the highest common strength step in JIS G3115. Buyers search JIS G3115 SPV490, SPV490 steel plate, SPV490 QT vessel plate, SPV490 equivalent and SPV490 supplier. The number is the yield idea: 490 MPa minimum. Tensile is 610–740 MPa. Delivery for this grade is quenched and tempered. That is why the title on this page is QT vessel plate, not a normalized carbon page.

This is not SPV450. SPV450 sits one step lower. This is not SPV410. This is not Q345R steel plate. This is not SA516 Grade 70. Quenched-and-tempered vessel plate is a different production route from normalized carbon plate.

SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) supplying JIS G3115 SPV490 to the USA, Europe, Middle East, Southeast Asia, Africa and South America.

Do not ship SPV450 steel plate against an SPV490 drawing. Do not ship SA537 Class 2 and call QT close unless both books are written and met. Dual marking is possible only when chemistry, tensile, impact and heat treatment all fit.

Company scope: global exporter SHH STEEL.

This plate sits in pressure vessel steel plates and JIS G3115. Heat-treated vessel comparisons also belong on ASTM A537 and ASME SA537.

Cast analysis follows JIS G3115. Product analysis is reported when the order names finished-plate chemistry. Google queries such as SPV490 chemical composition and JIS G3115 SPV490 chemistry should be answered from this table, not from an SPV355 table.

Cast Analysis and Product Analysis — JIS G3115 SPV490

Carbon stays limited because the strength comes from quenching and tempering, not from a high carbon melt. Residual nickel, chromium and molybdenum are controlled. This is still a carbon-manganese vessel plate family, not 2.25Cr-1Mo and not 9Ni. SHH STEEL reports heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search SPV490 mechanical properties, SPV490 yield strength and SPV490 tensile strength. Values below are the usual JIS G3115 idea. Thickness columns on the mill certificate govern.

Tensile and Yield — JIS G3115 SPV490

Do not quote 490 MPa yield on a plate that was only normalized. SPV490 on this page is a QT grade. Do not treat 610–740 MPa tensile as permission to stamp SA537 Class 2 or Q460R steel plate without checking both books.

Search habits mix SPV490 equivalent, JIS G3115 SPV490 equivalent and SPV490 vs A537 Class 2. Those names help a buyer find the right page. They do not authorize substitution.

Buyers pick SPV490 when a Japanese or export vessel file wants 490 MPa yield in the JIS G3115 family and the mill route is quench and temper. Search phrases such as SPV490 boiler plate, SPV490 pressure vessel plate and JIS G3115 SPV490 all point here.

It is not a substitute for 16MnDR steel plate. That grade is −40 °C low-temperature plate. It is not a substitute for 06Ni9DR steel plate. That grade is 9Ni. It is not Cr-Mo plate like 15CrMoR steel plate.

An ASME file that wants heat-treated carbon-manganese plate should name A537 / SA-537 on ASTM A537 and then write extras. 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.

SPV490 is quenched-and-tempered vessel plate at 610–740 MPa tensile. Treat welding as production welding, and as Code welding when the equipment is a vessel.

Qualify to the applicable code. Consumables must match the SPV490 tensile band. A procedure written for SA516 Grade 70 is normalized carbon practice and is not automatically valid. A procedure written for SA537 Class 2 is a comparison only. Preheat follows thickness and hydrogen control. Heat input and interpass matter because QT plate can lose heat-affected-zone toughness if the procedure is sloppy. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL is quenched and tempered JIS G3115 SPV490. Buyers who search SPV490 QT or SPV490 heat treatment are asking for this route, not as-rolled plate and not a simple +N carbon route.

If the vessel will see PWHT, say so. Test coupons then follow a simulated cycle. 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 JIS G3115 SPV490; heat number; cast analysis; product analysis when ordered; tensile; QT; impact when ordered. Certificates may be mill MTC plus EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for SPV490 QT vessel plate:

• Thickness: commonly 8 mm – 100 mm, thicker by mill agreement
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm

Lower JIS G3115 steps belong on SPV315 steel plate and SPV355 steel plate. Carbon vessel plate belongs on Q345R steel plate.

Dimensional limits follow JIS G3115 and the mill thickness table unless the order names JIS G3193 or another tolerance book. If the destination file was written to EN 10029 or SA-20, write that table on the purchase order. Do not apply ASTM A36 structural tolerances to a QT vessel plate without writing them.

Thickness minus tolerance should be named when the vessel calculation used minimum thickness after corrosion allowance. Flatness after quench and temper should be named when the plate will go to CNC cutting. QT plate can carry more residual shape than normalized carbon plate. Ask for flattening if the cutting bed needs it.

Charpy details. Temperature, energy, location and orientation.

Product analysis. Add this when the destination file wants finished-plate chemistry.

Simulated PWHT. When the equipment will be stress-relieved.

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

Through-thickness / Z-test. When written.

Third-party. EN 10204 3.2 when written.

SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). On JIS G3115 SPV490 that means mill pricing from Wuyang, Angang, Baosteel and other first-line mills, heat analysis reported, product analysis when ordered, recorded quench and temper, tensile to 490 / 610–740 MPa, 3.1 as standard and 3.2 when specified.

We keep the grade on the order. SPV490 is not SPV450. SPV490 is not SA516 Grade 70. SPV490 is not Q345R steel plate. If the drawing says SPV450, we will not ship SPV490 and call 490 better without the buyer writing the new name.
