Abstract

The invention provides a stainless steel material, belonging to the technical field of metallic material, and comprising the following components in percentage by weight: 0.06-0.09% of C, less than or equal to 0.6% of Si, 1.10-1.40% of Mn, less than or equal to 0.040% of P, less than or equal to 0.010% of S, 18.00-19.00% of Cr, 8.00-8.50% of Ni, 0.70-1.20% of Cu, less than 0.5% of Mo, 0.07-0.12% of N and the balance of Fe. Compared with the prior art, the stainless steel material provided by the invention improves the fatigue resistance and the corrosion resistance, reduces abrasion on a die to a certain degree, improves the product quality, and reduces the production cost.

Description

(1) Technical field [0001] The invention relates to a metal material, in particular to a stainless steel material that can be applied in the field of stainless steel spring wire and hanger wire. (2) Technical background [0002] At present, the materials used in stainless steel spring wire and hanger wire have the following problems: [0003] 1) When the drawn material is used to manufacture racks and pump head springs for cleaning products, it often fails the fatigue test and the corrosion resistance performance. [0004] 2) When the drawn wire is subjected to a bending test, there is a common defect that the fatigue resistance of the stainless steel wire cannot meet the needs of customers. The bending test of the hanger line shows that the number of bending is small, which causes the customer to break when bending. When the spring wire is used in the spring of the pump head of cleaning products, the fatigue test fails. The customer requested that the manufactured pump h...
