Classification of corrosion resistant alloys
I. Overview of corrosion resistant alloys:
Metal anti-corrosive materials. Compared with non-metal anti-corrosive materials, metal anti-corrosive materials mainly include iron-based alloys (corrosion-resistant stainless steel); nickel-based alloys (Ni-Cr alloy, Ni-Cr-Mo alloy, Ni-Cu alloy, etc.) ); Active metals.
Classification of corrosion resistant alloys:
1.Corrosion-resistant stainless steel
Mainly refers to ordinary 300 series stainless steels 304, 316L, 317L, etc. that are resistant to atmospheric or seawater corrosion; austenitic stainless steels 904L, 254SMO, which have strong corrosion resistance; duplex steels 2205, 2507, etc .; corrosion-resistant alloys containing Cu 20 alloy, etc .;
2.Ni-based corrosion resistant alloy
It is mainly Hastelloy and Ni-Cu alloys. Since the metal Ni itself has a face-centered cubic structure, its crystallographic stability enables it to accommodate more alloying elements than Fe, such as Cr, Mo, etc., to achieve resistance. A variety of environmental capabilities; meanwhile, nickel itself has a certain resistance to corrosion, especially the resistance to stress corrosion caused by chloride ions. In strong reducing corrosive environments, complex mixed acid environments, and solutions containing halogen ions, nickel-based corrosion resistant alloys represented by Hastelloy have absolute advantages over iron-based stainless steels. Our company has Alloy K 500 Bar for sale.
Alloy K 500 Rod
It also has very good anti-corrosion ability. Typical representatives are Ti; Zr; Ta; etc. Among them, the most typical representative is Ti; Titanium has a wide range of applications, mainly used in corrosive environments that some stainless steels cannot adapt to. Titanium material corrosion resistance principle: in an oxidizing atmosphere, a dense oxide film is formed to provide protection; therefore, it can not be generally used in a corrosive environment with high reducibility or tightness (anoxic environment). At the same time, The application temperature of titanium is generally less than 300 degrees Celsius. It is important to note that none of the active metals can be used in a fluorine-containing environment.
To share with you the main uses of Alloy K 500 Rod are: 1. Alloy rods are suitable for micro-drilling. 2. Alloy rods have good wear resistance and bending resistance. They are mainly used to produce extruded rods, which are suitable for wear parts such as general drills and knives. 3. Alloy rods have good abrasion resistance and bending resistance. They are mainly used to produce extruded rods, small diameter drill bits, clock processing tools, integral reamer and other cutting tools and wear-resistant parts. 4. The alloy bar is a kind of ultra-fine-grained tungsten steel material. This alloy bar has high hardness, good bending strength, wear resistance, and is not easy to chip and break. It is a special material for micro-drills. It is widely used in tungsten steel milling cutters, engraving cutters and wear-resistant parts.
