How to mark the specifications and models of stainless steel flat washers? 15 years of experience manufacturer + 20,000 sets of molds

Stainless steel flat washers, many friends often ask, how to mark the grade and material selection? What is the function of flat washers? Xiaoshuo sorted out a few points, let’s take a look with you: For 100HV grades ST12, ST13 and Q235, Q215, Q195, etc. can be used, and the surface hardness can reach about 110HV; for 140HV grades, 08F, 08Al and 10 can be used. , 10F, etc., the surface hardness can reach about 140HV; for 200HV and 300HV grades, 45, 50, 60, 70 steel or 65Mn steel should be selected, and it can be quenched and tempered by heat treatment to reach the technical requirements of 200~300HV and 300~400HV. Flat washers are usually thin pieces of various shapes that are used to reduce friction, prevent leakage, isolate, prevent loosening, or distribute pressure. Many materials and structures have such components, which are used to perform various similar functions. Limited by the material and process of threaded fasteners, the supporting surface of bolts and other fasteners is not large. Therefore, in order to reduce the compressive stress of the pressure-bearing surface to protect the surface of the connected part, washers are used. Hardware, 15 years of craftsmanship focused on stainless steel flat washers, 5000 square meters production workshop, 3 million punching production capacity per day, imported and national standard raw materials, 16 quality inspection layers strictly controlled, hundreds of precision processing production equipment, flat washers production accuracy Up to 0.01mm. It can quickly solve the problem of customizing time for flat washers, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose to rest assured!
