Some tested to stainless steel should applied in order can guarantee the product quality. The test that usually apply to stainless steel product such as tensile strength, hardness test, corrosion test and many other kind of test that can be different, depend on the purpose to use the steel. Stainless Steel Industry may stay in each country, and stainless steel supplier also can be from many country. The main raw material of stainless steel industry is use iron. The iron itself may don't available in the country so raw material should be imported from other country. This make the price of steel and stainless steel can be expensive.
Stainless Steel Stainless steel, also known as inox steel or inox from French inoxydable, chromium contain in this steel minimum 10.5% make this steel is stand to corrode. All types of stainless steel resist attack from low acid. Stainless types are 304. 316 and 317 and more type. Stainless steel 304 only stand to high pH like in NaOH, in low pH this steel have bad stand. Stainless steel type 304 is purpose for building construction or for support of piping line and many other use in Industry. Stainless 316 say as standard of molybdenum bearing grade, the best choose after stainless steel 304 because of this price is more higher than 304, so stainless steel 316 become second important to 304 among the austenitic stainless steel. Molybdenum contain in the steel make stainless steel 316 have better overall corrosion resistance properties than grade of 304, especially if use in acidic surrounded environment, such as in Chemical Industries. But for general purposes that need st...
