420 J2 Martensitic stainless steel NO.1 Coil

420J2 is a Martensitic stainless steel whose mechanical properties can be adjusted through heat treatment. In layman’s terms, it is a type of hardenable stainless steel. Typical grades are Cr13 type, such as 2Cr13, 3Cr13, 4Cr13, etc. After quenching, the hardness is higher, and different tempering temperatures have different combinations of strength and toughness. It is mainly used for steam turbine blades, tableware, and surgical instruments.

    Feature of Stainless Steel

    420J2: According to the difference in chemical composition, martensitic stainless steel can be divided into two types: martensitic chromium steel and martensitic chromium-nickel steel. According to the structure and strengthening mechanism, it can also be divided into martensitic stainless steel, martensitic and semi-austenitic (or semi-martensitic) precipitation hardening stainless steel and maraging stainless steel.

    Chemical Composition & Technical Request


    Stainless Steel Surface Finish of 2B/BA/Hairline/Mirror


    2B Finished: 2B finish is a mill finish, which is smooth and NOT the brushed finish commonly seen on kitchen appliances. 2B finish, light gray in color, may or may not have a protective film on one side to prevent scratching.

    BA Finished: Bright annealed (BA) finish is cold rolled stainless steel that is annealed in a controlled atmosphere to retain a highly reflective finish. Although it is not completely identical to the #8 mirror finish, it appears to be very similar. Generally speaking bright annealed finish has a PVC film on one side to help protect against scratching during fabrication and installation.

    8K Finished: 8K(#8) mirror has a non-directional finish that virtually looks like a mirror. It possesses a highly polished finish and does not contain or have a coating or finishing material to give it reflectivity. #8 mirror comes with a layer of PVC film to protect the mirror finish during fabrication and installation.

    NO.4/#4/Satin Finished: NO.4 (#4) finish is the brushed finish commonly seen on kitchen appliances and backsplashes. And it has a PVC film on one side to help protect against scratching during fabrication and installation.

    Hairline Finished: Hairline finish has long, continuous and uni-directional grind marks parallel to the longitude of the panel.By using specialized grinding technique, the grain size can be adjusted, as exemplified by defined hairline and scratch hairline. As a guideline, the quality of the finish is equivalent to that applied by the material provider.

    NO.1/#1/2D/2E Finished: NO.1 is a rough, dull and non-uniform finish, which results from hot rolling to the specified thickness, followed by annealing and descaling. It's generally used in industrial applications, such as equipment for elevated temperatures service, checker plate and etc.
