ABS grade A monohull steel 200 tons exported to Cairo

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for ABS grade A monohull steel various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several ABS grade A monohull steel after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

40Cr steel belongs to alloy structural steel. ABS grade A monohull steel, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the ABS grade A monohull steel steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of ABS grade A monohull steel seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.
