ASTM 316 316L Stainless Steel Bar 28mm 30mm

Now the most commonly used two kinds of Stainless Steel 304,316 L(or corresponding to the German/European standard 1.4308,1.4408), 316L and 304 in the chemical composition of the main difference is 316L containing Mo, and generally recognized, 316 corrosion resistance is better than 304 in high temperature environment more corrosion resistance. Therefore, in high temperature environment, engineers generally choose 316L material parts. But the so-called thing is not absolute, in the concentrated sulfuric acid environment, again high temperature do not use 316L! Or this is gonna be a big deal. Those of you who have studied mechanics have studied threads, and remember molybdenum disulfide (MoS2), a dark solid lubricant that is applied to prevent threads from biting at high temperatures, from which two conclusions can be drawn. [1]Mo is indeed a high temperature resistant substance. [2]: Molybdenum readily reacts with high sulfur ions to form sulfide. So no stainless steel is super resistant to corrosion. In the final analysis, stainless steel is a piece of more impurities of steel, steel can react with other substances.

Stainless steel round steel belongs to a class of long wood, also belongs to a class of bar, the so-called stainless steel round steel refers to the cross section of uniform circular long wood, generally about four meters long. It can be divided into light circles and black rods. The so-called light circle, refers to the smooth surface, after the quasi-rolling treatment; And the so-called black rod, refers to the surface of the black thick, hot rolled directly.

Stainless steel round steel can be divided into hot rolling, forging and cold drawing according to the production process. Hot rolled stainless steel round steel is 5.5-250 mm in size. Among them :5.5-25 mm small stainless steel round steel mostly to straight strips in bundles supply, commonly used for reinforcing bars, bolts and various mechanical parts; Stainless steel round steel greater than 25 mm, mainly used in the manufacture of machine parts or Seamless Steel Pipe billets.

Stainless steel round steel has broad application prospects, and is widely used in hardware kitchenware, shipbuilding, petrochemical, machinery, medicine, food, power, energy, aerospace, building decoration. Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.
