Production Flow of Carbon Steel Flat Bar
The Carbon Steel Flat Bar is made through three processes:
1.Feeding the material: Feeding the row material (the steel plate) to Slitting Line.
2.Slitting:The steel plate would be slitted into expected width by lengthways cutter.
3. Leveled and cutting: The plat bar would be ground into level by the grinder and then cut into required length.
FAQ:
Q1: What makes stainless steel stainless?
A1: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
Q2: Can stainless steel rust?
A2: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.
Q3: Why buy Materials & Equipment from ?
A3: All products offered by are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.
