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.
Steel grade1.4835 is a available as
machined round bar in dimensions 6 - 200 mm..
PLATE: 1-20mm thickness; 100-1500mm width
WIRE: 1-30mm diameter
STRIP: 0.5-4 thickness; 100-1219 mm width
Flat and SQUARE: 5-200 mm

As details at high temperature
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.
