Description

ASTM A312 UNS S30815 Super Austenitic Stainless Steel Pipe large diameter

1. 4835 (UNS S30815 – 253MA – SS2368)

253MA Stainless Steel is Rare Earth Metals (REM) and lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. 253 MA maintains its heat resistant properties by advanced control of micro alloy additions. The use of rare earth metals in combination with silicon gives superior oxidation resistance up to 2000°F. Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base alloys. A wide variety of components requiring high strength at elevated temperature such as heat exchanger, kilns, stack dampers and oven components are common applications for 253 MA.

Applications

Ø EN 1.4835 has a good weldability and can be welded using the following methods:

  • Shielded metal arc welding (SMAW)

  • Gas tungsten arc welding, GTAW (TIG)

  • Plasma arc welding (PAW)

  • Gas metal arc GMAW (MIG)

  • Submerged-arc welding (SAW)
  • Typical application areas for 1.4835:
  • Ovens
  • Construction
  • Building
  • As details at high temperature
Advantages
  • Corrosion Resistance
  • Heat Resistance
  • Heat Treatment
  • Welding
  • Machining

Function

By using 1.4835 (UNS S30815 – 253MA – SS2368) you get a Stainless High Temperature Steel designed to be used at temperatures over 550°C. It has a good resistance to oxidation and suits to be used as details in ovens, construction and buildings.

The steel grade 1.4835 ( also called UNS S30815, 253MA and SS2368) is an austenitic stainless high temperature steel with good resistance to oxidation. The steel has been designed to be used at temperatures over 550°C, the most suitable temperature range is 850-1100°C. The steel suits for production of details with good resistance to temperature corrosion and relatively high strength at elevated temperatures. It also has good creep strength properties. 1.4835 is not magnetic but can be slightly magnetic after cold working or welding.

Good formability and weldability
1.4835 has a good weldability and can be welded with shielded metal arc welding, gas tungsten arc welding, plasma arc welding and submerged-arc welding. You shall use low heat input and use filler metals of type EN 1.4835 when you weld. The steel can be both cold and hot formed but it can only be hardened by cold working. The steel has high hardness and at machining you need to follow cutting recommendations.

Possible alternative grades to 253MA grade stainless steel

Grade Why it might be chosen instead of 253MA
310 Carburising atmospheres require a higher nickel content
304H Lower cost alternative, provided the operating temperature is below about 800°C
Nickel Alloys Carburising atmospheres or temperatures above the 1100 - 1150°C maximum of 253MA.
