Brass product usually with dull-white color, different with bronze that usually in brown-yellow color, but people just say bronze color or brass color. The color, strength, machine-ability, and corrosion resistance of brass
are determined by the percentage of zinc and other metals present in the mixing of brass alloy. Brass alloy often use as trophy in sport competition because their color can resembles to silver.
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...
