Product Description:

 

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.
 
Why is 304 stainless steel somewhat magnetic?
 
Stainless steel is divided into austenite, martensite and ferrite.
 
304 material belongs to austenitic type. Generally speaking, it is non-magnetic or weak magnetic. However, because of the fluctuation of chemical composition or different processing conditions, magnetism may also occur. However, it can not be considered that magnetic products are not qualified. What is the reason? Austenite is non-magnetic or weak magnetic, while martensite or ferrite is magnetic.
 
Due to segregation or improper heat treatment in smelting, a small amount of martensite or ferrite structure will be produced in Austenitic 304 stainless steel. Thus, 304 stainless steel will have weak magnetic properties. In addition, 304 stainless steel after cold processing, the structure will also be transformed to martensite, the greater the deformation degree of cold processing, the more martensite transformation, the greater the magnetic properties of steel.

 

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.
