Skytech Rolling is a known manufacturer, trader and exporter of Stainless Steel 317 / 317L Square Bars, which is non-magnetic in the annealed condition but may become slightly magnetic after welding. Stainless Steel 317 Square Bars is annealed at 1010 Degree C – 1121 Degree C (1850 Degree F – 2050 Degree F) followed by cooling. SS 317L Square Bars is tougher than Stainless Steel 304 Square Bars with a long stringy chip, the use of chip breakers is recommended. One known exception in SS 317 Square Bars is highly oxidizing acids such as nitric acid to which the molybdenum - bearing stainless steels are less resistant. So, if your processes involve the use of very diluted (less than 3-4%) hydrochloric acid, mild concentration (10%) sulfuric acid, or sodium hydroxide (aka caustic soda), then SS 317L Square Bars might be worth the extra cost over SS 316 Square Bars or SS 304 Square Bars.
Alloy 317 Square Bars is readily welded by a full range of conventional welding procedures (except oxyacetylene). Alloy 317L Square Bars is an austenitic chromium-nickel stainless steel with excellent corrosion resistance, where its high Molybdenum content enhances the grade's superior pitting resistance. 317 Stainless SS Square Bars will provide better pitting (pinhole) corrosion resistance but at an increased cost. We prepared to discuss individual applications and to provide data and experience as a basis for selection and application of 317L Stainless SS Square Bars.
