Product Description
254SMO has good resistance to uniform corrosion. Especially in halide-containing acids, this steel is superior to ordinary stainless steel. Its C content is <0.03%, so it is called pure austenitic stainless steel (<0.01% is also called super austenitic stainless steel). Super stainless steel is a special stainless steel, which is first different from ordinary stainless steel in terms of chemical composition, and refers to a high-alloy stainless steel containing high nickel, high chromium and high molybdenum. Among them, the more famous is 254SMo containing 6% Mo, this kind of steel has very good local corrosion resistance,under the conditions of seawater, aeration, gaps, and low-speed erosion, it has good pitting resistance (PI≥40) and good stress corrosion resistance, and is a substitute material for Ni-based alloys and titanium alloys. Secondly, in terms of high temperature resistance or corrosion resistance, it has more excellent high temperature resistance or corrosion resistance, which is irreplaceable by 304 stainless steel. In addition, from the classification of stainless steel, the metallographic structure of special stainless steel is a stable austenitic metallographic structure.Because this special stainless steel is a high-alloy material, it is quite complex in the manufacturing process, and generally people can only rely on traditional processes to manufacture this special stainless steel, such as pouring,forging,calendering and so on.
Countersunk self-tapping screws are a type of screws with a flat head, countersunk head, or semi-countersunk head. Countersunk screws can also be called flat head screws, countersunk screws, semi-countersunk screws, and semi-countersunk screws. Generally, countersunk screws have cross grooves. Cross groove countersunk screws are commonly used in power equipment, electronic machinery, mechanical equipment, household appliances, digital products, water conservancy projects, decoration and construction, etc. Countersunk screws are generally made of metal screw wire, and the threads are rolled after forming. They are cylindrical and have a flat head, such as an inclined surface around the side of the screw, so that the screw can lock the nut or other objects.
