Material: 202 Surface: 2B / NO.1 Purpose: architectural decoration, hotel facilities, shopping malls, glass handrails, public facilities and other places Specifications: Complete specifications Origin: TISCO, Baosteel, Jiuquan brushed stainless steel surface is textured like filamentous , this is only a process of stainless steel. Matt surface is carefully to see if the slightest trace of texture above, but not out of touch. Abrasion resistant than stainless steel is generally bright side, look on some level. Stainless steel wire drawing board drawing board surface texture classification generally refers collectively add surface texture, matte board before it is called, there are several main lines ruled surfaces, arbitrary lines (and lines), corrugated and thread and so on. 1, drawing ruled. Usually after mechanical friction stainless steel surface to obtain a surface processing method of the state of a linear lines. Drawing board processing can eliminate scratches the surface of stainless steel materials, and also have a good effect decorative effect. Such lines are also silk filament lines and short lines, because this is the use of lines of stainless steel scouring pad or brush on the surface of the plate will be a straight line or short-term, and you can get different thickness of the lines by changing the diameter of the steel brush. 2, drawing arbitrary lines (and lines). From a distance the surface of the sand grain by grain composition circle around the sand, near the specification is not random pattern, by grinding up and down swing irregular ground, then plating coloring. This surface texture of the matte state, and the production is also high. 3, drawing ripples. Its production process is the use of brushing or wiping profiling group spend on axial movement of the roller, so that the stainless steel surface after grinding brush to get wavy lines. 4, drawing the threads. The characteristics of its production process a little, first with a small motor, its shaft with a circular felt, the small motor mounted on the desktop, but also with an edge angle of 60 ° around the table into. After making a carriage for fixing stainless steel sheet, but also posted a polyester film board again and again along the edge of the carriage, the purpose is to limit the speed of the thread. After such a felt can be rotated and moved linearly mop can be obtained the same width of the crests of the threads in the surface treatment of the stainless steel plate. Product Overview 202 stainless steel is 200 stainless steel one. A low-nickel 200 series stainless steel high-manganese steel, nickel content is generally below 4%, about 8% manganese, nickel stainless steel knots. 202 stainless steel is widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places. By precision automated system of equipment, pitting itself dissolved by welding, rolled forming, in the absence of any metal filler, the filled gas (outside of the tube) welded for TIG welding process, and for the vortex line solution testing.

These steel-hardening curve. 201 and 301 and 202 to 302 have similar hardening characteristics. 201,301 hardening larger. Generate the amount of martensite, each grade is different, 202,304 martensite generated very little, mainly by abnormal hardening process. 204,204L following steel hardening almost all rely on distortion. Mechanical properties and permeability CrMnN based material. These steels in the solution treatment state of hardness of about HV250, higher strength after cold rolling strengthening, Hv up to 500, but in this state, the magnetic permeability was still less than 1.005. [Product use 202 stainless steel is widely used in building decoration, municipal engineering, highway guardrail, hotel facilities, shopping malls, glass handrails, public facilities and other places.
