Components are exposed to extreme impact and abrasion loads in safety applications as well as in the extraction and processing of raw materials. durostat® HM sets new standards where conventional steels fail. durostat® HM is the hot-rolled hard manganese steel made by voestalpine and developed precisely for this purpose: reliably, resistant and sustainable with premium quality and a reduced carbon footprint.
durostat® HM is your best choice when it comes to maximum safety. The low material hardness in as-delivered condition (roughly 220 HB) makes durostat® HM easy to process. Impact and pressure during use increase the hardness near the surface up to 600 HB. Deeper areas remain ductile. Typical applications are security transport vehicles, vaults and security doors, where durostat® HM protects against violent attacks or breakthroughs.
Whether jaw crushers, blow bars or armor: durostat® HM withstands even the toughest impact and abrasion loads. The hardness increases in use to up to 600 HB, while deeper layers remain tough for maximum service life and safety.

Thanks to the austenitic microstructure, durostat® HM is characterized by very good weldability in common techniques such as MSG and manual electric welding. You can plan your welds on durostat® HM with the highest precision using the voestalpine Welding Calculator app or desktop version. The Welding Calculator helps you calculate cooling times, preheating temperatures and quantities of consumables.
durostat® HM is exclusively available in the greentec steel Edition with a reduced carbon footprint and sets new premium quality standards in the efficiency and sustainability in machinery.
In an effort to reduce our footprint even further and as a first step toward climate neutrality, all durostat® steels are available in the greentec steel Edition. greentec steel is sustainable voestalpine premium quality with a reduced carbon footprint.
