Austenitic stainless steel exhibits better strength retention than carbon steels at temperatures above about 550ºC and better stiffness retention at all temperatures. As a result, stainless steel columns can retain their load-bearing capacity for longer than equivalent carbon steel members. SCI Design Manual for Structural Stainless Steel.

Hiroshi Yamagata, in The Science and Technology of Materials in Automotive Engines, 2005. 5.3.2 Analysis of chemical composition of cast iron before pouring. Reusable raw materials, such as steel scraps from the body press process, are an abundant by-product of car manufacturing (Fig. 5.10).An electric furnace 6 melts the scrap with carbon (to raise carbon concentration) and ferro-alloys.

Stainless steel is manufactured in accordance with ASTM A 312 when 8-inch or smaller sizes are needed. There are eighteen different grades, of which type 304 L is the most widely used. Grade 316 L has high resistance to chemical and salt water corrosion, and is therefore used in applications where this characteristic is needed.
