Spring steel strip mainly includes hot-rolled round steel, square steel, flat steel and spring steel with special-shaped section. The surface of the steel shall be free from cracks, folds, scars, inclusions, delaminations and indented iron oxide scales. 65mn spring steel strip executive standard: GB/T1222-2007.
Shandong Xinhe International Trade Co., Ltd. is mainly engaged in 304, 201, 316L, 304L, 309S, 310S, 321, 430, 2205 dual-phase steel etc., stainless steel coils, plates, strips, laser cutting parts, etc. Matte, mirror, cutting, oil grinding, wire drawing, sheet metal, stamping products and other needs.
The use of line pipes has also expanded correspondingly with the rapid development of industry and agriculture. Therefore, hot-dip galvanized products are used in engineering construction (such as: curtain wall, power tower, communication power network, water and liquefied gas transportation, etc.), highway bridges, transportation; industrial production (such as chemical machinery and equipment, power engineering transportation, shipbuilding) etc. are widely used.
Galvanized steel pipe is divided into two types: hot-dip galvanized and electro-galvanized. The hot-dip galvanized galvanized layer is thick, the cost of electro-galvanized is low, and the surface is not very smooth.
The rust and corrosion resistance of stainless steel is due to the formation of a chromium-rich oxide film (passivation film) on its surface. This rust resistance and corrosion resistance are relative.
