410L Stainless Steel Rod Supplier in China
Stainless steel round steel belongs to the category of long products and also belongs to the category of rods. The so-called stainless steel round steel refers to a long material with a uniform circular cross section, which is generally about four meters long. It can be divided into light circles and black sticks. The so-called smooth circle means that the surface is smooth and has undergone quasi-rolling treatment; the so-called black rod means that the surface is black and rough and is directly hot-rolled.
Stainless steel round steel has a broad application prospect and is widely used in hardware kitchen utensils, shipbuilding, petrochemicals, machinery, medicine, food, power, energy, aerospace, etc., building decoration. Equipment for seawater use, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; photo, food industry, coastal facilities, ropes, CD rods, bolts, nuts.
Stainless steel round steel can be divided into three types according to the production process: hot rolling, forging and cold drawing. The size of hot rolled stainless steel round bar is 5.5-250 mm. Among them: 5.5-25 mm small stainless steel round bars are mostly supplied in straight bundles, which are often used as reinforcing bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used for manufacturing mechanical parts or seamless steel pipe .
