Welding Instructions for Weldox and Hardox steel plate, Svenskt Stål. 2. At ShapeCUT, we have 5,000+ tonnes of steel in stock, including quench and tempered plate, and the technical know-how and experience to craft it into any form imaginable. Tempering involves reheating the quenched steel plate to a temperature just below critical, then allowing it to cool at a predetermined rate. The process is tightly controlled, with the heating temperature, cooling method, cooling substance and cooling speed all dependent upon the type of material being quenched and the desired hardness. 0,14 0,45 0,25 0,95 3,25 0,25 Steels that require high yield strength, fatigue resistance to torsion and flexion, tolerate shear resistance slightly higher than its yield point in … Material is tested to check if it meets requirement. In the past, ductility and weldability came at a cost to strength and toughness. All categories Supplied to increase critical component lifespan. They are also called QT bars. The toughness-factor means greater resistance to wear and abrasion. Contact our team directly, Web Design & Development by ExtraMile Communications.

The resulting steel is brittle and stressed, requiring it to go through the second stage of the heat treatment process - tempering. Some of the common grades include: 80 Grade – a high strength, low alloy structural steel; 400 400 Grade – a high hardness, abrasion-resistant steel; and 500 Grade – a medium carbon, high hardness and abrasion-resistant steel. The toughness is restored by reheating it to 600°C, maintaining the temperature for a specific time, and then allowing it to cool naturally (Tempering). The high-strength quenched and tempered (Q&T) alloy steels used for structural purposes are essentially available only as grade A514 today. Grade B7M. It is a steel that combines high yield and tensile strengths with good notch toughness and excellent weldability and has a minimum yield strength of 690 MPa. The steel plate is water-quenched in a separate unit, usually being clamped down to avoid warping. Quenching and tempering achieves an extremely fine-grained and homogeneous microstructure. ASTM A193 Grade B7M bolts and studs are identical in chemistry to Grade B7 (quenched and tempered medium carbon alloy steel), but have lower strength requirements and require 100% hardness testing of all fasteners manufactured in the lot. RQT® 701 is one of the grades in the RQT® range of high strength quenched and tempered structural steel manufactured by Tata Steel which is one of Europe's largest steel makers. Want to get in touch? Likewise, the temperature of the cooling element needs to remain constant or the edges of the metal can wind up brittle. It is the combination of these two processes that produces a harder, tougher steel that’s more weldable and ductile than ordinary carbon steel.
