One month ago, we received order from surgical needles manufacturing plant who requests
440B stainless steel wire, which has higher hardness. Basic martensitic grades AISI 420 stainless steel
wire can only offer HRC 55 after heat treatment.
Through our drawn wire plant hard work, the 440B stainless steel wire, dia 0.5mm done, it's lightly drawn,
good smooth surface.
Customer really appreciates our cooperation and hope that both party find more chance to work together.
