The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of S460M steel steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special S460M steel materials and specifications can be ordered in advance.

Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, S460M steel. The main differences according to the classification are as follows: A needs no impact test, B needs room temperature impact test (20 degrees above zero), C needs zero degree impact test, D needs minus 20 degree impact test, and E needs minus 40 degree impact test. The most important characteristic of manganese steel plate is that under the condition of strong impact and extrusion, the surface layer rapidly hardens, but the core still maintains good toughness and plasticity, and the hardened layer has good wear resistance.

EN10083-3 27MnCrB5-2 steel plates usually need quenching and tempering are special application. Up to now, EN10083-3 27MnCrB5-2 steel plates are mainly applied in airplane, guided missile, weapons, railway, bridges, ships, vehicles, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on fields.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for S460M steel.

JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with S460M steel SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.

our company is leading supplier of API 5CT casing pipes in China. N80 oil casing pipes enjoy high size precision, good weld toughness, S460M steel good extrusion resistance, easy quality control and low cost features. Welcome to our company to purchase S460M steel API 5CT N80 and so on casing pipes.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
