Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of A572 Gr 50 high strength steel service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
The material used for the elbow is carbon structural steel or high-quality carbon structural steel 20#. These two materials can not only ensure that the carbon steel elbow has good hardness, strength and wear resistance, but also ensure the plasticity of the elbow, and ensure that the elbow will not be broken or wounded due to stress during forming. However, cast steel elbows are also used in some special piping systems. This type of piping system requires high mechanical properties of the elbow, and it is difficult to form by forging and other methods in the process.
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. A572 Gr 50 high strength 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.
Our company has the ability to produce all kinds of steel structure parts. At the same time, we can design drawings according to the requirements of customers, and process according to the drawings.
