Sitherm

premium-grade high-temperature and hot-work steel

SITHERM steel is used in dynamic loading, and the design and manufacture of ferrous as well as nonferrous metals and steels. SITHERM steel is used to manufacture complex tools, such as: moulds, die casting tools, high pressure die casting tools, cores, hot cutting and extrusion tools.

The tool surface is exposed to cyclic temperature variations and mechanical loadings. In response to this, SITHERM steel is characterized by:

• high tempering resistance,
• great toughness and
• ductility in hot in cold conditions.

Delivery condition: SITHERM steel is usually delivered in a soft-annealed condition.

The production of SITHERM is done with recycled steel scrap and not iron ore as is the case with some other steel production factories. The choice to use scrap results in lower carbon emissions and a less intense environmental footprint for SIJ Group during the steel manufacturing process.
