Adaptability in high temperature environment: according to GB/T3098.6-2014 standard, stainless steel 304 and 316 products within 100℃ does not affect the tensile strength, but more than 100℃ after every 100℃ temperature rise, tensile strength reduced by 5%, in more than 400℃ is not recommended to us Read More

The principle of stainless steel rust is to add chromium, forming chromium oxide protective film on the surface of the steel, in order to effectively block the contact between the steel and the air, so that the oxygen in the air can not enter the steel to produce chemical reaction, to achieve the Read More

The length of the bolt should be chosen appropriately, 1-2 tooth distances shall prevail after tightening the exposed nut. The tensile strength of bolts and the safety of nuts meet the design requirements. Clean the thread before use. If the thread is damaged, at least the nut can pass smoothly. Read More

Without surface treatment: take 304 as an example, without any surface treatment, stainless steel bolts generally salt spray test time for 48 hours, nut for 96 hours, but affected by the surface roughness of the product itself, do not rule out the possibility of rust for 48 hours. After processin Read More

Austenitic stainless steel is magnetic in theory, but the material in the process of cold working, due to stress changed part of the austenite organized, into martensite and ferrite, martensite structure increases along with the increase of the deformation of magnetic, while decrease with the incr Read More

304 and 316 are austenitic stainless steel series, the mechanical properties of the products are the same, the difference lies in the corrosion resistance of the products. The corrosion resistance of stainless steel is also conditional, a kind of stainless steel in one medium is corrosion resistant Read More
