316L stainless steel plate hot rolled pickled and annealed 2000mm width ASTM standard
Description:
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.
Only 316 and 316L are readily available in stock.
Corrosion Resistance
Excellent in a range of atmospheric environments and many corrosive
media - generally more resistant than 304. Subject to pitting and
crevice corrosion in warm chloride environments, and to stress
corrosion cracking above about 60°C. Considered resistant to
pitting corrosion in potable water with up to about 1000mg/L
chlorides at ambient temperatures, reducing to about 300mg/L at
60°C.
316 is usually regarded as the standard “marine grade” stainless
steel, but it is not fully resistant to sea water. In many marine
environments 316 does exhibit surface corrosion, usually visible as
brown staining. This is particularly associated with crevices and
rough surface finish. Consult hao Technical Assistance for specific
environmental recommendations.
There is usually no difference in corrosion resistance between 316
and 316L.
Specified Properties
These properties are specified for flat rolled product (316L 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.

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.
Machining
A “Ugima” improved machinability version of grade 316 is available
in round and hollow bar products. Ugima machines significantly
better than standard 316 or 316L, giving higher machining rates and
lower tool wear in many operations.
“Dual Certification”
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.
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.
