To resolve for you, 201 stainless steel with history and origin of the material - Precision stainless steel - Spring stainless steel belt | | 301 super stainless steel spring

It’s made of good quality high strength lowalloy steel specialized for steel strapping, quenched and tempered by “Highstrength steel strapping production line” that was self-designed developed andmanufactured, which makes the steel strapping have high tensile strength andexcellent toughness. Meanwhile a dense layer of Fe3O4 is formed on the steelsurface. And paint a dense layer of environmentally friendly water-based paintwith different color as request of clients, which greatly increases the rustresistance and aesthetics of the steel strapping. Finally, coat a dense layerof environmentally friendly water-based wax in order to enhances the anti-rustability, reduces the friction and improves the lubrication performance. Ribbon wound is widely used in manual andsemi-automatic packaging of cold-rolled coils, color-coated sheet, nonferrousmetal, steel wire, glass etc. Oscillated wound is widely used in onlinepackaging base on full automatic baling machine of cold-rolled coils in Steeland nonferrous metals enter

It's made of good quality high strength lowalloy steel specialized for steel strapping, quenched and tempered by self-designed which makes the steel strapping have high tensile strength andexcellent toughness. Meanwhile a dense layer is formed on the steelsurface, which is blue color. Finally, coat a dense layer of environmentallyfriendly water-based wax in order to enhances the rust resistance, reduces thefriction and improves the lubrication performance. Ribbon wound is widely used in manual andsemi-automatic packaging of hot-rolled coils, cold-rolled coils, variousstructural section, nonferrous metal, steel wire, glass etc. Oscillated wound is widely used in onlinepackaging base on full automatic baling machine of hot-rolled coils in steeland nonferrous metals enterprises. 

The high tensilestrength steel strapping is made of cold rolling plain carbon structural steeland high quality carbon structural steel which was blue tempered by Highfrequency induction heating,then painted or galvanized and waxed in the end.Itcan bear bigger tension, and have good resistance to impact,so it’s widely usedfor packing in   wood, paper, glass, stone, steel, metallurgy, non-ferrousmetal industry and so on. Main standard of steel strapping Chinese standardGB/T 25820-2010, European standards
