OVERVIEW
440 STAINLESS STEEL

440 stainless steel comes from the martensitic family of steels, which are primarily valued for their strength. 440 steel is unique not only as the strongest stainless steel available, but as one of the few varieties that can be heat treated through annealing, hardening, and stress relieving processes.

FREQUENTLY ASKED QUESTIONS

  • What is 440 stainless steel coil?

    >

    440 stainless steel is a high-carbon, martensitic stainless steel known for its high strength, hardness, and wear resistance.

  • What are the common applications of 440 stainless steel coils?

    >

    440 is the highest grade of cutlery steel on the market. It contains more carbon, allowing for high edge retention when properly treated.

  • How do you guarantee your 440 steel product quality?

    >

    Our 440 products undergo rigorous inspections during manufacturing, cutting, and packaging to ensure the highest quality. And 440 mill test certificate is also provided.

  • How does 440 stainless steel compare to 304 stainless steel?

    >

    316 is austenitic steels that can’t be heat treated,and 440 represents a good alternative.

  • How does the corrosion resistance of 440 stainless steel compare to other stainless steels?

    >

    440 stainless steel has good corrosion resistance but is not as resistant as other stainless steels like 304 or 316. Its corrosion resistance is best when fully hardened.

  • What industries commonly use 440 stainless steel coils?

    >

    Industries such as cutlery manufacturing, medical instruments, automotive, and aerospace commonly use 440 stainless steel coils for their high strength and durability​.

  • Can 440 stainless steel be welded easily?

    >

    Welding 440 stainless steel can be challenging due to its high carbon content. Preheating and post-weld heat treatment are typically required to prevent cracking.

  • Is 440 stainless steel magnetic?

    >

    Yes,440 stainless steel is magnetic in both the annealed and hardened conditions, unlike austenitic stainless steels like 304​.
