Common uses of stainless steel

However, in villages and cities, frequent cleaning is required to maintain their appearance in the wild. In heavily polluted industrial and coastal areas, surfaces can be very dirty and even rusted. However, to achieve the aesthetic effect in the field environment, nickel-containing stainless steel is required. Therefore, 304 stainless steel is generally suitable for curtain walls, side walls, roofs and other construction purposes, but in aggressive industrial or marine atmospheres, 316 stainless steel is best. 304 and 316 stainless steels are included in several master planning guidelines.

Because "duplex" stainless steel 2205 combines excellent resistance to atmospheric corrosion with high tensile and compressive strengths, this type of steel is also included in European guidelines. Commodity shapes, in fact, stainless steel is produced in full specification metal shapes and sizes, and there are many special shapes.

The most common commodities are made from sheet and strip, but also plate is used to produce special commodities, for example, the production of hot-rolled structural steel and extruded structural steel. And there are round, oval, square, rectangular and hexagonal welded or seamless steel pipes and other products, including profiles, bars, wires and castings. In order to better meet the aesthetic requirements of architects, various commercial surface finishes have been developed.

How is the tensile strength of stainless steel wire divided?

Compressive strength level of stainless steel screws.

Stainless steel bolts refer to bolts made of stainless steel, including stainless steel SUS201 bolts, stainless steel SUS304 bolts, and stainless steel SUS316 bolts.

The efficacy levels of stainless steel bolts, studs and studs are divided into 10 levels: from 3.6 to 12.9. The number before the decimal point means 1/100 of the tensile strength limit of the material, and the number after the decimal point represents 10 times the ratio of the yield limit to the tensile strength limit of the material.

There are seven levels of efficacy for nuts, ranging from 4 to 12. The numbers roughly indicate 1/100 of the minimum pressure the stainless steel nut is guaranteed to withstand. The domestic high-quality hardware production with good quality control - Youkou, has formed a sophisticated processing technology.
