ASTM A 709 Gr.50W Weather-resistant steel sheet
ASTM A709 Gr.50W Weathering Steel Plate is a low alloy, high strength structural steel plate developed according to ASTM (American Society for Testing and Materials) Standard A709. Where "50" indicates a minimum tensile strength of 50 ksi (approximately 345 MPa) and "W" indicates that the steel has good weathering properties.
Characteristics of ASTM A 709 Gr.50W weathered steel plate
Good weatherability: A709 Gr.50W weathering corten steel can form a dense rust layer on the surface, effectively preventing further internal corrosion, especially suitable for structural engineering in marine environments and harsh climatic conditions.
High strength and low alloy content: A709 Gr.50W corten steel structure, as a kind of low alloy high-strength structural steel plate, has high strength and toughness, which can meet the requirements of bridges, buildings and other structural engineering on the strength, toughness and durability of the material.
Optimise the ratio of alloying elements: A709 Gr.50W weathering steel By controlling the content of carbon, sulphur, phosphorus and other harmful elements, it reduces the sensitivity of weld cracks of steel plate and improves the quality of welded joints.
A709 Gr.50W steel plate has high strength and toughness, at the same time, it also has good fatigue resistance and certain low temperature toughness.A709 Gr.50W corten steel material can provide long service life and excellent corrosion resistance, is one of the important materials in structural engineering.
ASTM A 709 Gr.50W corten weathering steel is mainly used in bridges, buildings and other structural engineering, especially in the marine environment and harsh climatic conditions in the structural engineering has a wide range of applications.
