Hot Rolled Stainless Steel Strip Hot rolled stainless steel strip

Stainless steel hot-rolled belt, which is made of hot rolled stainless steel strip, which is made of hot rolled strip. Compared with cold strip, it has high precision, low surface roughness, surface quality, clean and high strength.

Stainless steel hot rolled belt

Stainless steel hot rolled belt introduced by shenzhen global stainless steel materials co., LTD. (gb4239-84).

Stainless steel hot rolled strip is made from hot rolled stainless steel strip, and it is made of hot rolling. Compared with cold strip, it has high precision, low surface roughness, good surface quality and light

Clean, and have a high intensity. Therefore, it can be used for the same purpose to reduce the amount of steel and the economic significance.

Hot rolled stainless steel strip according to the characteristic of divided into austenite size, austenitic grain size iron, iron grain size and martensite size as five kinds of precipitation hardening, when using can choose.

(1) main features and USES

(2) the number and chemical composition of the material

(3) mechanical properties

(4) size of strip steel

0.70, 0.80, 0.90, 1.00, 1.20, 1.20, 2.00, 2.50, 3.00, 4.00 mm.

Different editing of stainless steel hot strip and cold strip

Hot rolling is made of slab (mainly cast billet), which is heated and made into strip steel by roughing mill and finishing mill. From finishing the last hot steel strip mill out through laminar flow cooling to the set temperature, which consists of the winder coil, steel coil after cooling, according to the different needs of users, with different finishing line (flat, straightening, transverse or longitudinal cutting, inspection, weighing, packaging and logo, etc.) and become a steel plate, flat roll and longitudinal cutting steel strip products. Easy, a piece of steel billet after heating (that is, the TV that burn the red hot steel block) fine a few rolling, and trimming, correct as steel plate, this is called hot rolled.

Cold-rolled, hot-rolled steel coil for raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts. Hard roll can be used as the raw material of hot galvanizing plant, because the hot galvanizing unit is set up with annealing line. The hard rolled coil is generally 6 ~ 13.5 tons, and the steel rolls are under normal temperature, and the roll of hot rolled acid is rolled continuously. Inner diameter is 610 mm.

Product features: because there is no after annealing treatment, the hardness is very high (HRB is greater than 90), mechanical processing performance is poor, only simple has directivity of less than 90 degree bend processing (perpendicular to the direction of the winding).

Simpler, cold-rolled, is on the basis of hot-rolled coil processing rolling out, in general is hot-rolled pickling - - cold rolling process.

Cold rolling is made from hot rolled plate at normal temperature, although in processing, it also causes the steel plate to warm up, even though it is called cold rolling. Because hot rolling is cold rolled by continuous cold, the mechanical performance is poor, the hardness is too high. It must be annealed to restore its mechanical properties, and no annealing is called hard roll. A hard roll is usually used to make a product that does not bend, stretch, or bend on either side or side of the edge of a hard piece of hard luck.
