We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
Alloy 2507 with 4% Mo, 25% Cr, and 7% Ni is designed to be used in salt water. The Alloys 316 and 317L are thought-about to be enough for some marine environment applications corresponding to boat rails and hardware and facades of buildings close to the ocean, which are uncovered to salt spray. The Alloys 316 and 317L stainless steels all perform without proof of corrosion within the 100-hour, 5% salt spray (ASTM B117) test. Alloy 316/316L (UNS S31600/S31603) is a chromium-nickelmolybdenum austenitic stainless steel developed to supply improved corrosion resistance to Alloy 304/304L in reasonably corrosive environments.
Austenitic stainless steels are non-magnetic within the annealed, absolutely austenitic condition. The magnetic permeability of the Alloys 316 and 317L within the annealed situation is generally less than 1.02 at 200 H (oersteds). Permeability values for cold deformed materials differ with composition and the amount of cold deformation however are often greater than that for annealed material. The Alloys 316 and 317L exhibit wonderful resistance to oxidation and a low price of scaling in air atmospheres at temperatures as much as 1600 to 1650Â°F (871 to 899Â°C). The performance of Alloy 316 is generally somewhat inferior to that of Alloy 304 chrome steel which has barely higher chromium content (18% vs. sixteen% for Alloy 316).
Since the rate of oxidation is significantly influenced by the ambiance encountered and by operating circumstances, no actual knowledge may be presented which are applicable to all service situations. Alloys 316 and 317L are significantly more resistant than any of the other chromium-nickel types to options of sulfuric acid. At temperatures as excessive as 120Â°F (38Â°C), both varieties have excellent resistance to higher concentrations. Service tests are usually fascinating as working conditions and acid contaminants might significantly have an effect on corrosion fee.

Our stainless production range
- Alloy 317L containing 3 to four% molybdenum is most well-liked to Alloys 316 or 316L which comprise 2 to three% molybdenum in purposes requiring enhanced pitting and basic corrosion resistance.
- These alloys additionally provide larger creep, stress-to-rupture, and tensile energy at elevated temperatures.
- These alloys additionally offer greater creep, stress-to-rupture, and tensile power at elevated temperature.
- In addition to wonderful corrosion resistance and strength properties, the Alloys 316 and 316L Cr-Ni-Mo alloys also present wonderful fabricability and formability which are typical of the austenitic stainless steels.
D12b – Ba (Bright Annealed) Beveled
For the Alloys 316 and 317L the solution anneal is accomplished by heating in the 1900 to 2150Â°F (1040 to 1175Â°C) temperature range adopted by air cooling or a water quench, depending on section thickness. Cooling must be sufficiently fast via the 1500 to 800Â°F (816 to 427Â°C) range to keep away from reprecipitation of chromium carbides and provide optimum corrosion resistance.
As proven by the laboratory corrosion data below, these alloys supply glorious resistance to boiling 20% phosphoric acid. This is an element within the manufacture and handling of sure food and pharmaceutical products where the molybdenum-containing stainless steels are often required so as to decrease metallic contamination.
Minimum mechanical properties for annealed Alloys 316, 316L and 317L austenitic stainless steel plate as required by ASTM specifications A240 and ASME specification SA-240 are shown below. Both Alloys 316 and 317L are vulnerable to precipitation of chromium carbides in grain boundaries when uncovered to temperatures in the 800 to 1500Â°F (427 to 816Â°C) vary.
