Domex960MC High Strength Steel Plate


Domex960MC is a hot-rolled high-strength steel with a yield strength not less than 960MPA, mainly used in advanced lifting devices, mobile cranes and construction machinery. The delivery status is hot-rolled. The material is tested in accordance with EN 10149 and is the Swedish SSAB steel company's trump card product with a yield strength of 960 Mpa. The continuous delivery has been achieved and the performance is very stable. The quality of the stability is much better than ordinary high strength steel, the manufacturing process is more simple, with very good cold formability.


Bending:


The allowable small internal bending radius is 3,0 × thickness is 90o bending, two longitudinal and transverse bending directions. When bending the 960 there is a punch radius greater than the critical, smaller allowable bend radius.


Heat treatment and processing:


Domex960MC has obtained the mechanical properties of the temperature controlled rolling and control is not suitable for applications requiring thermal processing or heat treatment at temperatures above 400 ° C due to the material may lose its collateral


Welding:


Low carbon content, phosphorus and sulfur make all conventional welding methods. Domex960MC has low and high strength carbon equivalent. The general preheating is not the 960 due to the need for lean chemistry. To reduce the risk of hydrogen embrittlement cracking, the recommended fill metal, the large value of the weld metal is 5 ml / 100 grams hydrogen content.
