SUS420 J1 Stianless Steel Plate Price Per kg
Leave a message
With the increasing demand for tools, cutting tools, and industrial equipment, the cutting tool manufacturing industry prioritizes 420J1 stainless steel due to its moderate hardness and good edge retention. Global buyers tend to choose spot suppliers to shorten delivery cycles and ensure timely delivery. High-quality stock steel plates are in limited supply; GNEE's inventory ensures fast delivery and consistent quality.
If you are searching for 420J1 high-hardness stainless steel plates, GNEE can provide ready-to-ship inventory in multiple thicknesses from 4 mm to 50 mm, manufactured to JIS G4305 / ASTM A276 standards, with full ISO 9001, SGS, and BV certifications. Our plates are available in annealed, polished, and cut-to-length finishes, offering excellent hardness after heat treatment, superior wear resistance, and consistent quality for industrial knives, molds, and wear-resistant components.

What is SUS420J1 stainless steel sheet?
SUS420J1 is a martensitic stainless steel, commonly known as AISI 420J1. Its mechanical properties can be significantly improved through heat treatment processes such as quenching and tempering, making it suitable for applications such as knives, scissors, and other cutting tools. It exhibits optimal corrosion resistance in the quenched and tempered state, especially on surfaces that have undergone grinding or polishing. However, its corrosion resistance is generally not as good as that of austenitic stainless steels (such as 304 or 316).

What are the differences between SUS420J1 and SUS420 j2?
The main difference is that SUS420J2 is harder and has higher strength than SUS420J1 due to its higher carbon content. This makes SUS420J2 more suitable for applications requiring greater wear resistance, such as knives and surgical instruments, while SUS420J1 is more workable and has slightly better corrosion resistance for applications like decorative items and certain food processing equipment.
