ASTM A240 316/316l Stainless Steel Plate. In ASTM A240, type 316 and 316L is a chromium nickel austenitic steel, Element molybdenum addition can enhances corrosion resistance of stainless steel, which is the main factor that 316/316l is more corrosion resistant than 304/304l.
Heat Treatment of ASTM A240 TP 316L Stainless Steel Plates Annealing The austenitic stainless steels are provided in the mill annealed condition ready for use. Heat treatment may be necessary during or after fabrication to remove the effects of cold forming or to dissolve precipitated chromium carbides resulting from thermal exposures.
Jan 08, 2011 · REHeat treat of S.S. 316L 316 austenitic SS annealing temperature is 1040 1120 C. then generally followed by water quenched. Your time at temperature will depend on your thickness but generally isn't that long; just long enough for carbides to be in solution (few minutes).
Heat treatment may be necessary during or after fabrication to remove the effects of cold forming or to dissolve precipitated chromium carbides resulting from thermal exposures. For the Type 316 alloy the solution anneal is accomplished by heating in the 1900 to 2150° F (1040 to 1175° C) temperature range followed by air cooling or a water quench, depending on section thickness.
This specification covers chromium, chromium nickel, and chromium manganese nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications including architectural, building, construction, and aesthetic applications. ASTM A240 steel plate covers Austenitic Steels, Ferritic steels and Martensitic Steels.

NO.1 Finish PlateThe surface finished by heat treatment and pickling or processes corresponding there to after hot rolling.
Unlike martensitic steels, the austenitic stainless steels are not hardenable by heat treatment as no phase changes occur on heating or cooling. Softening is done by heating in the 1050/ 1120°C range, ideally followed by rapid cooling. This is of course the complete opposite to martensitic steels, where this sort of treatment would harden the steel.

Oct 23, 2001 · Stabilising heat to 870 900 °C for 1 hour per 25mm of thickness and air cool. Stabilisation is recommended for most severe service conditions (above 425 °C) and particularly for material annealed at the upper side of the annealing temperature range. Stress Relief Heat to 700 °C for 1 to 2 hours and air cool.
Type 316 (UNS S31600), Type 316L (UNS S31603) Description. Type 316/316L is a chromium nickel austenitic stainless steel containing molybdenum. The molybdenum addition enhances the corrosion resistance over that of 304/304L in halide environments as
Can SS 316L be heat treated at recrystallization temp. for achieving fine grains? Will carbide phases get dissolved at this temp.? What can be the probable cooling rate?
Sep 30, 2019 · Trying to find information on a Post weld heat treatment cycle for 410 to 316 stainless. It is in an reactor effluent stream. Any information would be great. John By Date 09 14 2005 22:17 The carbon content of the 410 goes a long way in determining what the preheat and PWHT temperatures are going to be. The thickness of the material and the
Aug 26, 2005 · what effect does heat treatment have on 304L @ 1600 f for 1 to 3 hours By Date 08 24 2005 18:55 Heat treating 304L for 1 3 hours can cause the steel to become sensitized. Sensitization occurs when the steel is held in the range of 800 1500F for the time you stated. During this time, chromium carbides will precipitate to the grain boundaries.
Stress relieving heat treatments for austenitic stainless steels Introduction. Unlike martensitic steels, the austenitic stainless steels are not hardenable by heat treatment as no phase changes occur on heating or cooling. Softening is done by heating in the 1050/
316 Hot Rolled Annealed and Pickled stainless is an "18 8" austenitic chromium nickel steel modified by the addition of molybdenum, which greatly increases the corrosion resistance as well as the mechanical properties at elevated temperatures. 316 is non magnetic in the annealed condition and not hardenable by heat treatment.
