Common features and the types of the shrapnel processing of materials - precision

30 years of professional experience in stamping custom shrapnel, dongguan by shrapnel process materials and features of different can be roughly divided into bronze shrapnel, spring steel shell and stainless steel shrapnel: stainless steel shrapnel good ductility, Cr and Ni content is low, stable chemical composition, steel purity, low inclusion content. Good surface quality, brightness is good. Have strong corrosion resistance. High tensile strength and fatigue strength. Stainless steel often according to the state of organization can be divided into: martensite steel, ferritic steel, austenitic steel, austenitic - Ferritic stainless steel and precipitation sclerosis stainless steel and bronze shell with good pressure resistance, resilience, corrosion resistance, good electrical conductivity, high shielding effect, long service life, etc. , thermal conductivity, high temperature resistance, long service life and reliability. Suitable for all kinds of shielding room, doors, chassis, door plate, printing plate board, integrated circuit block, etc. Spring steel shell with good comprehensive performance ( Elastic limit, ultimate strength, showed) Annor reduction performance, fatigue resistance, hardenability, heat resistant, good low temperature resistance, oxidation resistance, corrosion resistance, etc
