The grades of DUROSTAT B2 are boron alloyed, quenched and tempered steels, which are produced as fine-grain steels. The steels are mainly used for components of agricultural machines such as harrows and ploughs. Additional areas of use are wheel loader buckets, dump bodies or cut bars on front loaders.
The technical terms of delivery apply for plate thicknesses from 8 - 100 mm.
DUROSTAT B2 steels are produced via the LD-route.
The steel is fine-grain melted and can contain microalloying elements such as Nb and V.
The plates are delivered in as-rolled condition (hot-rolled, untreated), since usually heat treatment such as quenching or tempering is carried out on the finished parts.
Standard values for as-rolled conditions (plate thickness 20 mm)
Achievable hardness (following quenching in water)
48 - 52 HRC.
The heat analysis is provided as proof of the chemical composition.
Tolerances and surface finish
Unless otherwise agreed, tolerances according to EN 10029 (thickness tolerance according to class A, flatness tolerance according to class N) and surface finish according to EN 10163-A1 are valid.
In general, marking consists of:
Material testing certificate
Type of certificate according to EN 10204 must be agreed upon ordering.
