Welcome to BBN High Strength Steels Factory
45# seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of 45# seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. 45# seamless pipe is used to manufacture high strength moving parts.
Advantages of S690Q material equivalent: 1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel. 2. Good toughness and weldability. 3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required. 4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
S690Q material equivalent and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.
Due to the rapid development of the epidemic globally, many nations have moved to a position of “social distancing” in an effort to delay the spread of the COVID-19 virus. Cases have now been detected in most countries worldwide and community spread is being detected in a growing number of countries. The World Steel Association (worldsteel) has cancelled or postponed all our upcoming membership committee meetings. In a few cases they may go ahead electronically but the majority will be reconvened at a later date.
