316Ti stainless steel plate hot rolled pickled and annealed 2000mm width ASTM standard
Description:
316Ti stainless steel plate China brand 0Cr18Ni12Mo3Ti (with drawings 0Cr18Ni12Mo2Ti should also be this brand), the new brand is 06Cr17Ni12Mo2Ti stainless steel plate, 316Ti stainless steel plate is added to SUS316 steel to improve the resistance to intergranular corrosion. Equipment for resisting sulfuric acid, phosphoric acid, acetic acid, acetic acid.
Grade 316 is the standard molybdenum-bearing austenitic grade, second stainless steel in importance to 304. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It is readily brake or roll formed, welded, soldered and cut by both thermal and mechanical methods. The austenitic structure gives excellent toughness, even down to cryogenic temperatures.
Grade 316L, the low carbon version of 316, is highly resistant to sensitisation (grain boundary carbide precipitation) and so is extensively used in heavy gauge welded components (about 5mm and over).
Grade 316H, with its higher carbon content has some application at elevated temperatures, as does stabilised grade 316Ti. Nitrogen-strengthened versions also exist as 316N and 316LN.

Welding
Excellent weldability by all standard fusion methods, both with and without filler metals. AS 1554.6 pre-qualifies welding of 316 with Grade
316 and 316L with Grade 316L rods or electrodes (or their high silicon equivalents). Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance. This is not required for 316L. Grade 316Ti may also be used as an alternative to 316 for heavy section welding.
It is common for 316 and 316L to be stocked in “Dual Certified” form, particularly in plate, pipe and round bar. These items have chemical and mechanical properties complying with both 316 and 316L specifications. Such dual certified product may be unacceptable for high temperature applications.
Corrosion Resistance
There is usually no difference in corrosion resistance between 316 and 316L.These properties are specified for flat rolled product (316Ti stainless steel plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.
Typical Applications:
Food processing equipment. Laboratory equipment. Architectural panelling, railings & trim. Boat fittings. Chemical containers. Heat exchangers. Screens for mining, quarrying & water filtration. Threaded fasteners. Springs.
