Parameters

400 series stainless steels typically contain chromium (Cr) as the primary alloying element and varying amounts of carbon (C). The carbon contributes to their martensitic structure, which provides high hardness and strength. Common grades within the 400 series stainless steel include 410, 410S, 420, 430, 439, and 441.

Common Applications

400 series stainless steel alloys, known for their high strength, hardness, and wear resistance, find application in various industries. It’s important to note that while the 400 series stainless steels excel in strength and wear resistance, they may offer a different level of corrosion resistance than the 300 series stainless steels. Here are some common uses and applications of the 400 series stainless steels:

♦ Cutlery and Kitchenware: 400 series stainless steels, particularly grades 410 and 420, produce cutlery, knives, blades, and kitchen utensils.
♦ Bearings and Valves: 440 steel is utilized in the production of bearings, valves, and other components requiring high strength, hardness, and wear resistance.
♦ Cutting Tools: High-carbon stainless steel alloys from the 400 series, like grade 440, fabricate cutting tools such as industrial knives, razor blades, and shears.
♦ Pump & Valve: 410 and 416 stainless steel are utilized to manufacture pump and valve components. They can withstand abrasion in fluid-handling systems.
♦ Automotive Components: These applications include exhaust systems, mufflers, catalytic converters, and decorative trim.
♦ Mold and Tooling: Due to its high hardness, 420 stainless steel is commonly used to produce molds, dies, and tooling for various manufacturing processes.
♦ Surgical Instruments: 410 stainless steel is often employed in manufacturing surgical and dental instruments. Surgical tools, dental picks, and orthopedic implants can use 400 series stainless steel for construction.

Whether for large architectures or shops, you can always expect the highest quality from us. Even in the extremely quality-sensitive art sector, our 400 series stainless steel products are recognized by the most famous artists.

Frequently Asked Questions

Q1. Are you a factory, manufacturer or trader?

A1. Foshan TOPSON Stainless Steel Co., Ltd. is a professional stainless steel factory with nearly 15 years of experience in stainless steel production. All our goods are dispatched directly from the TOPSON mill.

Q2. How can you ensure the quality of your product?

A2. Our stainless steel sheets and coils have to go through TWO/THREE checks in the manufacturing process, including production, cutting sheets (If requested) and packing.

Q3. There are a lot of 400 series; which is the best for you?

A3. 410 stainless steel offers good corrosion resistance, moderate strength, and high hardness. It suits cutlery, surgical instruments, valves, and pump parts; Grade 420 steel provides higher hardness and wear resistance than 410. It is commonly used in blades, surgical equipment, mold components, and cutting tools; Grade 430 exhibits good corrosion resistance, especially in mild environments. It is commonly used for decorative purposes, automotive trim, appliances, and architectural applications. 440 stainless steel is a high-carbon martensitic alloy known for exceptional hardness and wear resistance. It is suitable for applications requiring high strength, hardness, and sharpness, such as knives, cutting tools, and bearings.
