Welding & Cutting

Dimensional Tolerances & Surface Quality

Thickness As per EN 10029- Class A/B/C/D as per requirements.
Length and Width As per EN 10029.
Flatness As per EN 10029 Class N steel type H
Surface Properties As per EN 10163-2. Class A Subclass 1
Plate Ultrasonic Testing As per EN 10160 SO.EO

Cold Forming

Welding Method Lower carbon equivalent of Rockstar plates results in good weldability. All conventional welding methods like manual electric welding, submerged arc welding, inert gas welding can be applied
Thermal Cutting Rockstar plates are compatible with all thens, cutting processes including one plasina, and laser Preheating or 100 to 150°C is recommended for plates thicker than 20 men (10 mm for Rockstar 5001. Excess prereating above 200 C may reduce the hardness of Rockstar
