According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw LR EH32 pile-driving barge steel steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the LR EH32 pile-driving barge steel market due to the impact of the closure of local steel mills in Italy.
The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, LR EH32 pile-driving barge steel steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.
In 30th,Dec,2018--2th,Jan,2019, One Malaysian customer come to visit our factory to inspect their goods about CCS-AH36 steel plate. This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, LR EH32 pile-driving barge steel shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of products.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than LR EH32 pile-driving barge steel. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel LR EH32 pile-driving barge steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. LR EH32 pile-driving barge steel, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
Aspire to technological innovation and pursue first-class quality steel LR EH32 pile-driving barge steel products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.
