This product is a cold-rolled 590TRIP high-strength steel plate with excellent elongation characteristics and appearance grade, which can be used as the first automobile outer panel in the world.
2.2 JFE Steel's anti-oxidation coating steel plate JAGTM
This product is an anti-oxidation coating steel plate for hot pressing, which is designed to reduce the weight of automobile parts and has excellent oxidation resistance and corrosion resistance.
2.3 Kobe Steel
①KSG series high strength cold forged gear steel
This product has high strength gear steel with the same strength as Cr-Mo steel, and can improve the cold forgeability and improve the service life of the metal mold.
②TBF type 1180MPa cold-rolled high-strength steel plate for automobile
This product combines high-strength and high-strength steel plates with light weight of the car body and improved collision safety. It is used for the first time in the world as the main component of the body frame.
2.4 High reliability and long life bearing steel Premium J2 of Sanyang Special Steel
This product is a high-reliability pure bearing steel that makes it possible to miniaturize bearings on the basis of new steelmaking technology and testing technology.
2.5 Japanese high-frequency cold work tool steel KD11 MAX
This product is a universal cold work tool steel that can improve the service life of metal molds and improve the ease of mold making in the stamping of thin metal plates.
3 Industrial Machinery
3.1 High temperature mold steel QT41-HARMOTEX for Shanyang Special Steel
This product is a high-temperature die steel that not only reduces the content of alloy elements, but also further optimizes the metallographic structure of the steel, so that it has higher toughness and tempering stability than the original material.
4 Electrical machinery
4.1 Nippon Steel & Sumikin
①Fine grain stainless steel plate for finishing
This product is a stainless steel plate with SUS304 system grains reduced to 5 μm, which is effective for preventing surface roughness after bending.
② New beautiful steel plate NS coated zinc plate
This is to enable users to omit the painting process, and use the outer coating to achieve the aesthetic and corrosion resistance of the steel plate.
5 Energy sector
5.1 Nippon Steel & Sumikin
①High corrosion resistance duplex stainless steel pipe SM2502-65 for oil and gas pipelines
The use of this steel pipe does not require heat treatment after welding, and the product has sufficient resistance to stress corrosion cracking, and its cost is lower than the current steel pipe.
②High-strength H2S corrosion-resistant low-alloy oil well pipe SM-125ES
This 125KSI grade oil well pipe has the highest level of H2S corrosion resistance in the world, and is suitable as an oil well pipe for the development of large depth oil and gas.
③ Grade 80 for marine structures
It is the first time in the world to develop a class 80 thin steel plate, which was developed for the construction of large marine structures in the Gulf of Mexico, which is rich in oil and gas resources.
5.2 TMCP type stainless steel composite plate for oil and gas pipelines of JFE Steel Corporation
This product has excellent strength, toughness and corrosion resistance of the base material, and it is a economical TMCP type composite steel plate for oil and gas pipelines.
5.3 Nippon Steel & Sumikin Stainless Steel, low-nickel duplex stainless steel NSSC 2120, which can be welded with large line energy
This steel has twice the strength of SUS304 steel and has excellent weldability. It is a resource-saving duplex stainless steel that can replace SUS304 with reduced nickel content.
