Cause of corrosion pits on astm a633 grade e equivalent

The company received new orders from Peru customer for more than 900 tons of ASTM A36 steel plates astm a633 grade e equivalent. These A36 steel plates will be used in the "Belt and Road" project - a mining conveyor project in Peru. This is our long-cooperated customer, who purchased thousand tons of A36 steel plates from us every year. And make our astm a633 grade e equivalent A36 steel plates well known in local.

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

astm a633 grade e equivalent, Q460 material is a low-alloy high-strength steel. Q stands for the strength of steel. 460 means that plastic deformation occurs only when the strength of the steel reaches 460MPa. That is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape. This strength is greater than that of ordinary steel. Tensile strength is 550-720MPa, elongation: 17%, Q460 material is made by adding Cr, N, V, Ti and other alloying elements on the basis of 16Mn steel.

Mechanical Properties A242 steel:
ASTM A242 specification is made for low alloy steel with high strength, it has good atmospheric corrosion resistance, some applications has shown that it has better corrosion resistance than ASTM A36 steel and ASTM A572 Grade 50.
Tensile: 70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4)
Yield: 50 ksi min (3/4 and under), 46 ksi min (3/4-1.5) 42 ksi min (over 1.5-4)
Elongation: 16% min in 8” 19% min in 2” (for plates wider than 24”)
