ASTM A709 carbon steel plate sheet chemical and mechanical property

In recent years, in line with the development trend of iron and ASTM A709 carbon steel plate sheet steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which ASTM A709 carbon steel plate sheet are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

ASTM A709 carbon steel plate sheet, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with ASTM A709 carbon steel plate sheet ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for ASTM A709 carbon steel plate sheet various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several ASTM A709 carbon steel plate sheet after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
