What is stainless steel cold heading wire
Stainless steel cold heading wire refers to stainless steel cold heading steel wire, mainly austenitic stainless steel, with low yield strength. Cold heading steel requires materials with low deformation resistance and good plasticity.
The composition and ratio of stainless steel cold heading wire are: 0.08%-0.15% C; 0.01%-0.60% Si; 0.02%-0.60% Mn; 0.01%-0.03% P; 0.002%-0.03% S 12%-14% Cr; 0.8%-1.5% of Mo is Fe.
The preparation method comprises the following steps: performing molten steel smelting according to chemical composition requirements; hot rolling; annealing and pickling to obtain stainless steel disk blank; coating and drying; cold drawing; cleaning and drying with neutral activator; quenching; tempering Coating and drying; drawn into stainless steel cold wire. This high-performance stainless steel cold wire is energy-saving and environmentally friendly, with high corrosion resistance, high elasticity and high toughness. The preparation method and process are advanced and simple, and the production cost is low. Stainless steel cold wire is usually more than 1.0mm in diameter and is commonly used in the manufacture of nuts, screws, washers, brackets, bolts, etc. Copper is added to the raw material, which has good formability; low processing stress; excellent surface quality; good work hardenability, low mold loss rate, and low magnetic properties after cold forging.
Common materials are: 201, 202, 302, 304, 316, 302HQ, 304HC, 316L
Stainless steel cold heading 200 series stainless steel and 300 series stainless steel, both of which are austenitic stainless steel.
Features:
First, high dimensional accuracy, up to ±0.01mm;
Second, excellent surface quality, good brightness;
Third, strong corrosion resistance, high tensile strength and fatigue strength;
Fourth, chemical composition stability, steel Pure quality, low inclusion content; well-packaged, price concessions;
Five, not easy to headshot.
Stainless steel cold heading wire is mainly used to make fasteners such as screws and bolts.
There are two main aspects affecting the cold heading performance of steel wire:
1) It is an annealing process, the annealing process is different, the structure of stainless steel is different, and different microstructures affect the cold forming properties of the material.
2) It is an alloy composition system of stainless steel, and different additive elements will affect the material properties of the material. For example, low carbon content reduces the strength of the material, and low yield strength is important for cold forming. The 200Cu in the 200 series and the 304HC in the 300 series add the alloying element Cu to the 200 and 304, which improves the coldness of the material.
