420 stainless steel round bar suppliers
420 stainless steel round bar is a kind of martensitic stainless steel bars, with a certain degree of wear resistance and corrosion resistance, high hardness characteristics.
Advantages of 420 stainlss steel round bars as the followings:
1.Excellent corrosion resistance;
2.Excellent optical polishing;
3.Excellent abrasion resistance;
4.Excellent mechanical properties;
5.It has excellent stability when quenching;
6.Lower maintenance costs after long-term use of the mold, the mold cavity surface is still maintained the original smooth state.Mold in the wet environment, or when the operation, do not need special protection.
7.Lower production costs,because the cooling water channel of the mould is not affected by the corrosion (unlike common die steel), the heat conduction characteristics and cooling efficiency are kept stable during the die life.
420 Stainless steel round bars using condition,the use of 420 steel quenched and tempered state (hardness 48-54HRC), in order to meet the number of long-term work or product of 1 million or more life requirements, more suitable methods should be done using quenching and low temperature tempering treatment. The quenching is first heated to 1000-1050 DEG C heat preservation time (30 /25mm calculation), and then quenched into oil cooling to 50-100 DEG C and immediately tempering, to prevent cracking.Tempering at 200 degrees (at least 4 hours) can reach more than 48HRC, with a better polishing performance and better corrosion resistance.
