Stainless Steel SS304 DIN912 M6-M20,Internal Hexagonal Bolt Cylindrical Internal Hexagonal Screw
Product Description:
The inside hexagon screw head is round on the outside and concave in the middle, and the hexagon screw is the kind of common screw head whose side is hexagonal. Internal hexagonal screw is often used in machinery. It has the advantages of easy tightening, disassembly and not easy sliding angle.
1. We select stainless steel materials and adopt excellent stainless steel. The requirements of working conditions on corrosion resistance of materials are very high.
2. Products with high temperature resistance, acid resistance, alkali resistance, long service life, strong oxidation resistance, usually used in more valuable machine parts as fasteners.
3. The product has fine workmanship, beautiful appearance, meticulous surface treatment and durability.
What is the difference between 304/316 stainless steel and 304/316 stainless steel?
304 material has high tensile strength and yield strength, cold work hardening rate, good cold forming performance and corrosion resistance. High temperature resistance, good mechanical properties, rust-free characteristics, deeply trusted by the majority of users, widely used in curtain walls, side walls, roofs, outdoor equipment and other architectural purposes, but in the corrosive industrial or marine atmosphere, it is best to use 316 stainless steel.
The nickel content of 316 material is higher than 304 material, so its corrosion resistance and high temperature resistance are much better than 304 material. It is widely used in chemical and medical equipment, marine and petrochemical equipment manufacturing, but the price is much higher than 304 material, although the cost is higher, because of its strong corrosion resistance, it is also worth the money.
