ASME SA 53 seamless pipe is a low carbon TM rolled GL-FH 32 shipbuilding steel steel pipe with carbon content of 0.25% and manganese content of 0.95%. BBN exports all sizes of seamless, black welded and hot-dip galvanized TM rolled GL-FH 32 shipbuilding steel steel pipe of ASME SA 53. It is also known as soft steel pipe and is easy to produce.
Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.
TM rolled GL-FH 32 shipbuilding steel, Nickel-based alloys are widely used in petrochemical, metallurgy, energy, and machinery because of their high room temperature and high temperature strength, good oxidation and thermal corrosion resistance, excellent creep and fatigue resistance, good structural stability and reliability. , Building materials, medicine, environmental protection and other industries. The company has developed N08825, N06625, N06600, N06690, N06601 and other nickel-based alloy tube blanks and steel pipe products, which have been implemented in batches in the petrochemical industry.
The chemical composition difference between TM rolled GL-FH 32 shipbuilding steel, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between TM rolled GL-FH 32 shipbuilding steel, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
