The material has superior welding and forming qualities. These alloys also offer higher creep, stress-to-rupture, and tensile strength at elevated temperatures. SS L Stainless Steel Plate packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

In addition to excellent corrosion resistance and strength properties, the Alloys and L Cr-Ni-Mo alloys also provide excellent fabricability and formability which are typical of the austenitic stainless steels.

Historical Version s - view previous versions of standard Work Item s - proposed revisions of this standard Translated Version s: However, because of their greater strength and work hardenability, the power requirements for the austenitic grades during forming operations are considerably greater than for carbon steels.

Such "sensitized" steels are subject to intergranular corrosion when exposed to aggressive environments. Analyses Tested See footnote.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete wstm up to date. In general, asym that do not corrode stainless steels will not attack these molybdenum-containing grades. Grade will require post-weld annealing to promote maximum corrosion resistance, though this is not necessary if Type L is used. SS L Stainless Steel Plate packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage.

Fully austenitic weld deposits are more susceptible to cracking during welding. Typical applications for this material are now widespread due to its superior corrosion resistance properties when compared to Grade L.

Historical Version s - view previous versions of standard. Under Third Party Inspection. This abstract is a brief summary of the referenced standard. Where short periods of exposure are encountered, however, such as in welding, Alloy L with its higher chromium and molybdenum content, is more resistant to intergranular attack than Alloy for applications where light gauge material is to be welded.

Origins satm the Paper Industry The steel was initially produced for the paper producing industry as it has been shown to be highly resistant to the sulphur compounds used in paper processing.

Home About Site Map Resource. Two important considerations for weld joints in these alloys are 1 avoidance of solidification cracking, and 2 preservation of corrosion resistance of the weld and heat-affected zones.

Attention to lubrication during forming of the austenitic alloys is essential to accommodate the high strength and galling tendency of these alloys. 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. asttm

This specification covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. Clear labels are tagged on the outside of the package astmm easy identification of the quantity and product I.

One known exception is highly oxidizing acids such as nitric acid to which the molybdenum-bearing stainless steels are less resistant. Great care is taken during operation and transportation. The material shall conform to the mechanical properties specified.

Small quantities of ferrite may or may not be present. Impact Resistance of ASTM A TP L Stainless Steel Plates The annealed austenitic stainless steels maintain a high level of impact resistance even at cryogenic temperatures, a property which, in combination with their low temperature strength and fabricability, has led to their extensive use in cryogenic applications. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

The ability of the stainless grades to maintain clean surfaces often allows better heat transfer than other metals having higher thermal conductivity.

In every case, the metal should be cooled from the annealing temperature to black heat in less than three minutes. These alloys are blanked, pierced, and formed on equipment essentially the same as used for carbon steel.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Type stainless can be found in heat exchangers, pharmaceutical equipment, dairies and breweries, marine fittings, coastal architectural fascia and axtm and in food preparation areas.

Representative Charpy V-notch impact data for annealed Type at room temperature are shown below.
