The Use Of Stainless Steel Spring Wire

- May 02, 2018 -

Various stainless steel materials have different characteristics due to their different material contents, so the corrosion resistance is also different.

304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability).

301 stainless steel shows a significant work hardening phenomenon during deformation and is used in various applications requiring higher strength.

302 stainless steel is essentially a variant of 304 stainless steel with a higher carbon content, which can be obtained by cold rolling.

302B is a kind of stainless steel with high silicon content. It has high resistance to high temperature oxidation.

303 and 303Se are free-cutting stainless steels that contain sulfur and selenium, respectively, and are used in applications where high lightness and high lightness are primarily required.

303Se stainless steel is also used to make parts that require hot boring because the stainless steel has good hot workability under these conditions.

304L is a variant of 304 stainless steel with a low carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may cause intergranular corrosion in some environments (weld erosion).

304N is a nitrogen-containing stainless steel. Nitrogen is added to increase the strength of the steel.

316 (18Cr-12Ni-2.5Mo) material: Due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and it can be used under harsh conditions; excellent work hardening (non-magnetic). Uses: papermaking, oxalic acid, fertilizers and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.

Spring wire hardness is as follows: full soft | 1/4 hard | semi-hard | 3/4 hard | full hard | Specifications: Ф0.08mm~Ф12.6mm.

The use of stainless steel spring wire: the hardness of stainless steel spring wire causes their different uses, generally used as small elastic products in life, but also for vehicle springs, compression springs, which are widely used in normal life. Stainless steel spring wire within the species: In terms of appearance, the spring line is generally divided into matte spring line and bright surface spring line, matte spring line hardness is brighter than the bright surface spring line, can be used as hanging line, generally used In products with low appearance requirements and relatively high elasticity requirements.
