Flat washers for fasteners, standard introduction + 15 years of ingenuity and focus on manufacturers

Flat washers for fasteners, there are currently 9 items in my country's flat washer standards. Xiaoshuo sorted it out and came to understand with you: From 2000 to 2002, GB/T97.3-2000, GB/T5286-2001, GB/T95-2002, GB/T96.1-2002, GB/T97.3-2000, GB/T5286-2001, GB/T95-2002, GB/T96.1-2002, GB/ T96.2-2002, GB/T97.1-2002, GB/T97.2-2002, GB/T97.4-2002 and GB/T5287-2002 and other flat washer standards. According to the performance level of flat washers, Xiaoshuo recommends the use of materials: For 100HV grades, ST12, ST13 and Q235, Q215, Q195, etc. can be selected, and the surface hardness can reach about 110HV; for 140HV grades, 08F, 08Al and 10, 10F can be selected 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 reach 200-300HV and 300-400HV technical requirements through heat treatment, quenching and tempering. According to the standard, flat washers of 100HV and 140HV grades can be made of low carbon steel. Most companies generally use Baosteel materials when selecting materials, which is convenient for cold stamping.
