ASTM 420 Stainless Steel Bar 20Cr13 UNS42000 Forged Rod
Stainless steel bar stock is a standard type of steel material that is manufactured from stainless steel raw materials. It is regularly used to produce a wide variety of metal parts, products and components. The material can be used to create nuts, bolts, and screws. The reason that large fastener manufacturers use these steel bars to create such important pieces is that the machinery that will utilize the screws and bolts needs to withstand weight and cold.
Stainless steel tape/strip/band usually classify as following :304 304L 303 302 301 430 201 202 316 316L stainless
steel tape/strip/band,among which there is a much higher content of nickel and chromium in 309 310 314 than than
others, so as to improve high temperature oxidation resistance and creep strength of steel, while 310s stainless steel
strip which has lower carbon content than 310, is variants of 310 stainless steel. As a result ,310s can minimize the
precipitation of carbides near the weld .330 stainless steel has great carburizing resistance and high thermal shock
resistance. 310 carbon content<=0.25%,while 310s carbon content<=0.08%
