Product Overview

420 series hot rolled stainless steel plates, including 420, 420J1 and 420J2, are martensitic stainless steels known for their excellent hardness, wear resistance, and moderate corrosion resistance after heat treatment. These grades are widely used in applications requiring high strength and edge retention, making them ideal for industrial tools, blades, and mechanical components.

Grade Comparison
Grade Carbon Content Hardness Corrosion Resistance Main Features
420 Medium High Good General-purpose martensitic steel
420J1 Lower Medium Better Higher corrosion resistance, softer
420J2 Higher Higher Slightly lower Better hardness & wear resistance

Key Features
  • Excellent hardness after quenching (up to HRC 50+)
  • Good wear resistance for long service life
  • Moderate corrosion resistance
  • Good machinability in annealed condition
  • Suitable for heat treatment (quenching & tempering)
  • Cost-effective compared to high alloy stainless steels
Typical Applications
  • Knife blades & cutting tools
  • Industrial machinery parts
  • Surgical instruments
  • Mold manufacturing
  • Shafts, valves, and pump components
  • Wear-resistant components
Heat Treatment
  • Annealing: 750-850°C, slow cooling
  • Hardening: 980-1050°C, oil or air quenching
  • Tempering: 150-370°C depending on required hardness

Advantages Over Other Grades
  • Higher hardness than 304 / 316 stainless steel
  • Better wear resistance than austenitic grades
  • Lower cost compared to high alloy tool steels
  • Flexible options (420J1 vs 420J2) for different applications
Packaging & Delivery
  • Export standard seaworthy packing
  • Wooden pallet + waterproof protection
  • Delivery time: 7-20 days
  • Global shipping supported

Frequently Asked Questions
What is the difference between 420J1 and 420J2?
420J1 has lower carbon content, offering better corrosion resistance and ductility. 420J2 has higher carbon content, resulting in higher hardness and wear resistance.
Can 420 stainless steel be hardened?
Yes, 420 stainless steel can be heat treated to achieve high hardness (up to HRC 50+), making it ideal for cutting tools and blades.
Is 420 stainless steel corrosion resistant?
It has moderate corrosion resistance, suitable for general environments, but not as resistant as 304 or 316.
What industries use 420 stainless steel plates?
It is widely used in cutlery, medical tools, molds, machinery parts, and industrial components.
What surface finish is available for hot rolled plates?
Common finishes include black surface, annealed, and pickled surface.
