White Point: White spot is actually a tiny crack in the earlier sample was radioactive transvese irregular jagged crack, low times in the longitudinal sample is circular or elliptical star silver highlights, so called white spots . (The main cause is the cause of hydrogen) shrinkage: shrinkage cavity contraction in steel in the form of liquid steel called cratering. Transverse: refers ingot surface transverse cracks occurred 304 stainless steel pipe supplier, usually in ingot, generally shallow depth, the grinding can get rid of. Diastema: refers to longitudinal cracks ingot surface, usually in ingot upper portion and the corner portion 304 stainless steel tube, while the upper part of a deep crack, it is difficult to eliminate grinding. Scarring: ingot surface, like skin or shell-like build-up of metal splashed sticky called scarring, scarring often seen in the lower part of the ingot. Heavy Leather: At the edge of the low times of the test piece 304 stainless steel pipe distributors, showing a dark irregular loose, gathered around a large number of oxide inclusions (mainly ferrous oxide) called capsized. ? Why are rusting stainless steel pipe when the surface of brown rust (points), people great surprise: that "Stainless steel is not rust, rust is not stainless steel, the steel may be a problem." In fact, this is a lack of understanding of the stainless steel one-sided view of the error. Stainless steel under certain conditions will be rusty. Stainless steel has the ability to resist atmospheric oxidation of stainless steel --- that is, while also having acid, alkali, salt corrosion medium capacity --- that is corrosion resistance. But its size is the corrosion resistance of steel itself with its chemical composition, plus mutual status, conditions of use and environmental media type change. Such as 304 stainless steel tube 304 agents, in a clean dry atmosphere is absolutely excellent anti-corrosion ability, but to move it to the waterfront, contains a lot of salt in sea mist will soon be rusty ; and 316 steel is performing well. So instead of any kind of stainless steel, in any environment corrosion resistant, not rust. 304 stainless steel pipe sales, 304 stainless steel pipe, stainless steel supplied by Chi Yu, Foshan City, Chi Yu Stainless Steel Materials Co..
