a573 steel grade 58 iron plate flaw detection process

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the a573 steel grade 58 iron plate project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of a573 steel grade 58 iron plate customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

We are world class steel materials supplier and exporter. Our main steel materials are: carbon and hsla steel, boiler and pressure vessel steel, gas cylinder steel, shipbuilding and offshore platform steel, pipeline steel, weathering steel / corten steel, a573 steel grade 58 iron plate alloy steel, automobile structure steel, abrasion resistant steel, clad steel, stainless steel etc.. Meanwhile, we also have steel processing center, and can provide cutting, welding, bending, drilling etc. processing for steel materials.

a573 steel grade 58 iron plate annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of a573 steel grade 58 iron plate annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. a573 steel grade 58 iron plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

The chemical composition difference between a573 steel grade 58 iron plate, 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 a573 steel grade 58 iron plate, 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.
