253MA/ UNS S30815 Seamless Stainless Steel Pipe

• General introduction of 253MA/ UNS S30815 Seamless Stainless Steel Pipe:
  • 253 MA / UNS S30815 was developed over 30 years ago when the need for a heat resistant stainless steel with high strength, while maintaining good oxidation resistance was present in the industry
  • The leaner nickel content of 253 MA was not as significant of a development then as it is now
  • With nickel prices fluctuating more than ever before and higher than they have ever been, the lean 11% nickel content of RA 253 MA is a key contributor to being cost effective and stable. Still with the addition of rare earth elements, 253 MA still performs well at temperatures up to 2000°F (1093°C), similar to that of 310 stainless steel
• Performance of 253MA/ UNS S30815 Seamless Stainless Steel Pipe:
  • 253 MA/ UNS S30815 is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance
  • It offers an excellent combination of creep strength along with excellent resistance to oxidation, sulfidation, and erosion at high temperatures in an alloy containing just 11% nickel
  • Because of its lean chemistry, 253 MA is very economical compared to most heat resistant alloys
• 253MA / UNS S30815 obtains its heat resistant properties by tight control of micro alloy additions
• The use of cerium in combination with silicon results in superior oxidation resistance to 2000°F (1093°C)
• Nitrogen, carbon, and cerium combined to provide creep rupture strength that is double that of type 310 and 309 stainless at 1600°F (871°C).
• Features of 253MA/ UNS S30815 Seamless Stainless Steel Pipe:
  • Oxidation resistance to 2000°F (1093°C)
  • Good resistance to sulfidation
  • Superior strength at elevated temperatures
  • Good resistance to high temperature abrasion
