420 stainless steel coil/strips is a martensitic stainless steel, which has the typical characteristics of martensitic steel. It has good malleability in the annealed state, and will have high hardness and strength after heat treatment. 420 steel is widely used in industries such as tool manufacturing, mechanical parts manufacturing, medical devices, and valve manufacturing.
What are the core advantages of the cost performance of 420 stainless steel coils?
1.The performance meets the requirements
Processing performance: The heat treatment process is relatively simple (usually quenching at 980-1030°C and tempering at 150-370°C), with a small tendency of work hardening, and the manufacturing cost of the cutting tool is reduced.
Basic performance balance: Hardness can reach HRC50-55, maintaining basic cutting ability. Containing 12-14% chromium, it provides acceptable anti-rust performance and meets the daily usage requirements.
2. The production cost is low
Simple composition: Compared with 440 series stainless steel, the 420 model reduces the ratio of carbon and chromium elements, and does not add high-valent alloy components such as molybdenum and vanadium, which significantly reduces the cost of raw material procurement.
