  • Corrosion resistance of stainless steel

    introduction: Types and definitions of corrosion A stainless steel may have good corrosion resistance in many media,But in some other medium,However, corrosion may occur due to low chemical stability。so,A stainless steel cannot resist corrosion in all media。 Among many industrial uses,Stainless steel can provide satisfactory corrosion resistance。Based on experience with use,Except for mechanical failure,The corrosion of stainless steel is mainly manifested in:A serious form of corrosion of stainless steel is local corrosion(Thats stress corrosion cracking、Pitting corrosion、Intergranular corrosion、Corrosion fatigue and crevice corrosion)。These failures are caused by local corrosion

  • Heat treatment of die parts

    introduction:Heat treatment requirements for each part of blanking die: Blanking is one of the basic processes of cold stamping。It is a stamping process in which the blanking die is used to separate the blanking material on the press。A blanking die is a die with a cutting edge。The cutting edge sinks into the material being flushed during blanking,And withstand the strong impact and intense friction of the material,The cutting edge will be seriously worn after a period of use,Sharp from the beginning、Eventually it becomes round and dull,The quality of subsequent products is affected。In order to ensure the long-term stability of the quality of parts,This requires the punch of the die to have high wear resistance,And also have a certain compressive strength、Bending strength
