Understanding Stainless Steel Grades WESBUL-09080-US-1302 www.westlockcontrols grade of ss Stainless steel designations There is a broad variety of designations for stainless steel grades by different international testing and standards organisations worldwide. Each is based on the materials chemical Type 316/316L Stainless Steels Explained Marine-grade stainless steel, called type 316, is resistant to certain types of corrosive environments. There is a variety of different types of 316 stainless steel. Some common types are the L, F, N, and H variants. Type 304 and 304L Stainless Steel Explained This grade has slightly lower mechanical properties than the standard 304 grade, but is still widely used thanks to its versatility. Like Type 304 stainless steel, it's commonly used in beer-brewing and wine-making, but also for purposes beyond the food industry such as in chemical containers, mining, and construction.
904L is an austenitic stainless steel.In comparison to 316L, its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids and in particular its copper addition gives it useful corrosion resistance to all concentrations of sulphuric acid. SAE 316L stainless steel - Wikipedia SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel. Its primary alloying constituents after iron , are chromium (between 1618%), nickel (1012%) and molybdenum (23%), with small (<1%) quantities of grade of ss Related searches grade of ss

While standard ferritic steels are, by far, the largest consumer group in terms of tonnage, demand for specialty grade stainless steels is increasing steadily.
These grades are indicated by the letter H after the stainless grade number. The use of this designation would be when the end-use involves an extreme temperature environment. Type 304: One of the most commonly used (Austenitic) Stainless grades. Austenitic stainless steel - Wikipedia Austenitic stainless steel is one of the five classes of stainless steel by crystalline structure (along with ferritic, martensitic, duplex and precipitation hardened).Its primary crystalline structure is austenite (face-centered cubic) and it prevents steels from being hardenable by heat treatment and makes them essentially non-magnetic. stainless steel | Definition, Composition, Types, & Facts grade of ss There are more than 100 grades of stainless steel. The majority are classified into five major groups in the family of stainless steels: austenitic, ferritic, martensitic, duplex, and precipitation-hardening. Austenitic steels, which contain 16 to 26 percent chromium and up to 35 percent nickel, usually have the highest corrosion resistance.
Martensitic Stainless Steels . Martensitic stainless steels are also based on the addition of chromium as the major alloying element but with a higher carbon and generally lower chromium content (e.g. 12% in Grade 410 and 416) than the ferritic types; Grade 431 has a chromium content of about 16%, but the microstructure is still martensite despite this high chromium level because this grade grade of ss Stainless steel grade chart - Atlas Steels Stainless steel grade chart ATLAS STEELS SPECIALTY STEELS PRODUCT REFERENCE MANUAL SECTION 9: APPENDICES Printed November 2000 1 S9 Chemical analysis (%) specied Grade UNS No. C Si Mn P S Cr Mo Ni Other 253MA S30815 0.05 1.1 - 2.0 0.8 0.040 0.030 20.0 - 22.0 10.0 - 12.0 N 0.14-0.20-0.10 Ce 0.03-0.08 Stainless Steel Tube | Stainless Tube | Stainless Tubing | Tubing We stock an extensive inventory of high-quality standard and special grade of seamless stainless steel tube and welded stainless steel tubing.

The most commonly specified austenitic (chromium-nickel stainless class) stainless steel, accounting for more than half of the stainless steel produced in the world. This grade withstands ordinary corrosion in architecture, is durable in typical food processing environments, and resists most chemicals. Stainless Steel - Grade 410 (UNS S41000) Grade 410 stainless steels are resistant to hot gases, steam, food, mild acids and alkalies, fresh water and dry air. These steels obtain maximum corrosion and heat resistance through hardening. However, grade 410 steels are less corrosion resistant than austenitic grades and grade 430 ferritic alloys containing 17% chromium. Stainless Steel - Grade 316 (UNS S31600) Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
