With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate A514 grade E structural steel material shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.
A514 grade E structural steel material, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.
BBN steel various machining process service for A514 grade E structural steel material products. Flame cutting is a traditional thermal cutting method. The thickness of the cut metal ranges from 1 mm to 1.2 meters. However, when the thickness of most of the low carbon steel plates you need to cut is below 20 mm, other cutting methods should be used. In order to cut accurately and effectively, the operator needs to have superb skills to avoid the thermal deformation of the metal plate in time during the cutting process.
