Cold Rolled Polish bright finish 3*20mm Stainless Steel flat steel 304
Stainless Steel flat steel 304:
Categories and specifications :
It can be divided into two categories: equilateral and unequal sides. The equilateral side can also be divided into square steel specifications expressed by the size of edge length and edge thickness. At present, the domestic specifications are 3mm*20m-150mm.

Heat treatment:
It is annealed in the temperature range of 850-1050 ºC, then annealed rapidly, and then cooled rapidly. 316 stainless steel can not be hardened by heat treatment.
Welding:
304 stainless steel has good weldability. All standard welding methods can be used for welding. According to the use, 316, 304 or 316L stainless steel Flate steel or electrode can be used for welding. In order to obtain the best corrosion resistance, the welded section of 304 stainless steel needs to be annealed after welding. If 304 stainless steel is used, post-weld annealing is not required.
Factory supply inspection before shipment,sampling test( cut one piece for you to test in our lab or some other lab like SGS TUV which you trust )

What Is Your Export Package?
Interleave paper, Waterproof paper,metal belt pack the sheet, wooden pallet.For stainless Steel sheet/coil,if wooden box needed,that is also no problen for us,best packing is needed in SINO stainless steel.
What Is Your Delivery Time?
Normally 5-7 day after advance payment received or Orignal L/C at sight.(Just for regular size of stainless steel coil)
Where Is Your Main Market?
South America, Mid East, Eastern Asia, Central Americ outh Asia inculding You.
