Product Overview

Our 420J2 and 316L stainless steel sheets are engineered to meet the most demanding industrial and commercial needs, combining specialized material properties with precision manufacturing. 420J2 is a high-hardness martensitic grade perfect for wear-resistant applications, while 316L is a low-carbon austenitic grade renowned for exceptional corrosion resistance in harsh environments. Both grades comply with international standards, making them trusted choices for global importers, manufacturers, and contractors.

Core Features

420J2 Stainless Steel Sheet

✅ High Hardness & Wear Resistance: Heat-treated hardness up to HRC 55, ideal for applications requiring scratch and impact resistance (e.g., cutlery, molds, surgical tools).

✅ Excellent Machinability: Easy to grind, polish, and form into complex shapes without cracking.

✅ Cost-Effective Performance: Balances durability and affordability for high-volume production.

✅ Rust Resistance: Moderate corrosion protection suitable for indoor or mild outdoor use.

316L Stainless Steel Sheet

✅ Superior Corrosion Resistance: Molybdenum content provides 2x better protection against saltwater, acids, and chemical exposure than 304 grade—perfect for marine, chemical, and medical environments.

✅ Low-Carbon Weldability: Minimal carbide precipitation during welding, preventing intergranular corrosion in welded structures.

✅ Food & Medical Grade: FDA and EU compliant, safe for food processing equipment, surgical instruments, and pharmaceutical machinery.

✅ Temperature Stability: Maintains mechanical properties from -40°C to 870°C, suitable for high-temperature industrial processes.

Frequently Asked Questions (FAQ)

Q: What’s the main difference between 420J2 and 316L stainless steel sheets?

A: 420J2 is a martensitic grade with high hardness and wear resistance, ideal for tools and cutlery. 316L is an austenitic grade with superior corrosion resistance, suitable for marine, chemical, and medical applications. 420J2 is magnetic after heat treatment, while 316L is non-magnetic.

Q: Can I get custom-sized 420J2 or 316L stainless steel sheets?

A: Yes! We offer custom cutting to any size or shape, including circular blanks, rectangular plates, or complex geometries. Simply share your CAD drawings or specifications, and we’ll provide a tailored quote within 24 hours.

Q: Do you provide free samples?

A: Yes, we offer free 10x10cm samples (you only pay for shipping). We can send both 420J2 and 316L samples to help you test material properties before placing bulk orders.

Q: Are your stainless steel sheets food-grade compliant?

A: Our 316L stainless steel sheets are FDA and EU food-contact approved. 420J2 is suitable for food processing tools but not direct food contact unless polished to a food-safe finish.

Q: How long does shipping take to the USA/EU?

A: Stock orders arrive in 7-10 days via air freight; bulk orders take 25-30 days via sea freight. We offer expedited shipping for urgent requests.
