Why laser cutting keeps JIS carbon steel SM490A CS plate with precise size

EN10025-3 S460N high-strength steel has high strength, especially in normalizing or normalizing and tempering state. It has higher comprehensive mechanical properties. S460N plates are mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. S460N mechanical properties: tensile strength Rm500-680MPa, yield strength: 420-320MPa, elongation after fracture 18-19%.

The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seamless steel pipe is hot rolling or hot expanding. There are many materials for large diameter seamless steel pipe, such as JIS carbon steel SM490A CS plate, which can be processed and customized according to customer requirements. The large diameter seamless steel pipe is usually used in the chemical, petroleum, mechanical and other industries.

JIS carbon steel SM490A CS plate Tianjin inventory: 7*2920*8200, 15*2992*10185, 40*3050*5800, 14*1950*10700, 50*2500*12000, 20.9*2851*7000, 16*2120*6080, 20*1950*9350, 26*2200*12000, 20*2933*7300, 12.5*2900*11000, 40*3050*4200, 20*1950*9750, 15*2992*10185, 16*2230*7650, 14*2150*8500, 50*2200*12000, 16*2120*6080, 70*2500*12000.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and JIS carbon steel SM490A CS plate pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
