After heat treatment and cold drawing hardening, 65MN manganese steel wire has high strength, certain toughness and plasticity; under the same surface condition and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, it has poor hardenability and is mainly used for smaller-sized springs, such as pressure-regulating and speed-regulating springs, force-measuring springs, round and square spiral springs on general machinery, or springs drawn into steel wires for small machinery.

65Mn strip steelis a commonly used spring steel with a wide range of uses and advantages. It is mainly composed of elements such as carbon, silicon, manganese, phosphorus and sulfur, and has high strength, high toughness, good heat treatment properties and wear resistance.
65Mn strip steelis an ideal material for manufacturing various springs, such as automobile suspension springs, industrial machinery springs, electrical appliance springs, etc.
65Mn strip steelhas high hardness and wear resistance, so it is suitable for manufacturing various cutting tools, such as saw blades, blades, stamping dies, etc.
65Mn strip steel is suitable for manufacturing various mechanical parts, such as bullets, bolts, nuts, pins, etc.
65Mn strip steelcan be used to make spring steel strips, which are widely used in automobile manufacturing, home appliance manufacturing, construction and other fields. Spring steel strips have good elasticity and toughness and can be used to manufacture various spring products, such as suspension systems, mattresses, door locks, etc.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
