Products Description

ASTM A709-50W is a standard specification for structural steel primarily in the fabrication of steel bridges. ASTM A709-50W covers high strength, low allow steel structural shapes, plates and bars.

The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition. ASTM A709-50W shall have an atmospheric corrosion index of 6.00 or higher.

The chemistry of an astm a709 gr 36 steel Seamless Pipe may contain any of the following elements carbon, sulfur, silicon, manganese, phosphorus, and copper in a specified limit.

A tension test administered on the astm a709 grade 50 steel pipe could be used to circumscribe the expected tensile properties. Generally, tensile tests detail parameters such as tensile and yield strength in addition to elongation properties as well. Materials for the astm a709 grade 50w weathering steel Pipe are mandated to undergo the following tests.

First, an impact test is conducted on the specimen for both the non-fracture critical as well as the fracture critical members. Next, the specimen of ASTM A709 Pipe is subjected to a Brinell hardness test for Grades 100 and 100W. It is required to check the ASTM A709 Grade 50W Pipe for atmospheric corrosion resistance.
