We Can Supply A Wide Range Of Steel And Other Metal Products
Stainless Steel
Material: AISI 316, UNS S31600, 1.4401/1.4436
316 stainless steel is created by adding molybdenum and nickel to 304 stainless steel, and belongs to the austenitic stainless steel series. 316 steel has a high temperature resistance of 1200-1300 degrees due to the addition of M0 element. Due to its excellent performance, 316 stainless steel pipes are widely used in medical device manufacturing, pharmaceutical and food industries, chemical industries and other fields.
Duplex & Super Duplex
Material: Grade S32760, DIN 1.4501, F55
Duplex steels S32760 and F55 are resistant to various inorganic and organic acids. The added copper element makes them resistant to non-oxidizing acid corrosion. S32760 is also resistant to strong alkali corrosion. However, duplex steels S32760, F55, and 1.4501 are not suitable for use at long-term working temperatures above 300°C, because above this temperature, the toughness of the material will drop significantly.
Nickel Alloy
Material: Alloy 31, N08031, 1.4562
Alloy 31, also known as VDM Alloy 31, 1.4562, UNS grade N08031, is a new type of austenitic nickel-iron-chromium alloy containing 6.5% molybdenum and nitrogen. It has strong corrosion resistance to pitting and crevice corrosion, and is even better than traditional 6-Mo steel in many applications.
Hastelloy Steel
Material: Hastelloy X, UNS N06002, 2.4665
Hastelloy X is a nickel-based alloy with good oxidation and corrosion resistance, medium and long-lasting strength below 900°C, and good cold and hot processing formability and welding performance. It is suitable for manufacturing combustion chamber and other high-temperature components of aircraft engines, with long-term use below 900°C and short-term working temperature reaching 1080°C.
Incoloy Steel
Material: Incoloy 825, UNS N08825, 2.4858
Incoloy 825 (UNS N08825, 2.4858)is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. Alloy 825 is similar to alloy 800 but has improved resistance to aqueous corrosion. The high nickel content makes the alloy effective against stress corrosion cracking.
Stainless Steel
Material: AISI904L, N08904, 1.4539
904L is a low carbon austenitic stainless steel designed for use in severe corrosive conditions. Compared to 316L, 904L stainless steel has more chromium, nickel, molybdenum, and copper. Therefore, 904L steel is more wear-resistant and heavier, but there is not much difference in hardness. 904L stainless steel is also called "rolex 904l​", which means that Rolex uses 904L to make watch cases.
