Introduction of St37-2 carbon structural steel
ST37-2 is a common structural steel, which is used in construction and underground engineering. T37-2 is a carbon structural steel material grade in Germany, which corresponds to China's equivalent of carbon structural steel Q235B (old number: A3-B), mainly used in construction and underground engineering. In addition, because this steel is similar to China's high-quality carbon structure steel 20 steel, it is also useful to replace 20 steel.
St37-2 implementation standard: German steel standard,DIN17100
Third, ST37-2 steel plate delivery status: hot rolling, probe rolling, normalizing.
4. St37-2 Manufacturer:
St37-2 steel plate manufacturers Wugang, Baosteel, Nangang, Angang, Shougang, Xiangang, Xinyu.
Fifth, St37-2 steel plate flaw detection and Z requirements
St37-2 steel plate thickness extension can be done; Z15, Z25, Z35
St37-2 steel plate thickness flaw detection can be done; One probe, two probe, three probe
The thicker the thickness of St37-2 steel plate, the more difficult the inspection is, and the common specification 20-130 can ensure a probe,
Six, ST37-2 steel plate application
ST37-2 is mainly used for riveting, bolted connection and welding purposes. Structural steels such as ST37-2 are used in many applications with both good weldability and guaranteed strength. There are many grades and uses including civil and industrial engineering. High strength low alloys have replaced many structural steels where weight reduction is important but still have guaranteed strength (such as in automobiles). It is used in construction and underground engineering.
Seven, St37-2 steel plate surface quality:
Cracks, bubbles, scarring, folding and blending are not allowed on the surface of St37-2 steel plate. If there are such surface defects, cleaning is allowed. The cleaning depth shall be calculated from the steel plate practice standard and shall not exceed half of the thickness tolerance of the steel plate, and the minimum thickness of the steel plate shall be ensured. The depth is calculated from the steel plate practice standard, shall not exceed half of the steel plate thickness tolerance, and shall ensure that the thickness of the defect is not less than the allowable thickness of the steel plate.
