US dollar economic stimulus plan will boost China A514 grade Q steel material export

Before laying, if there is bending deformation, it should be corrected in time. The A514 grade Q steel material steel plate shall be installed, straightened and welded according to the requirements of the drawing. The corrugated plate shall be straight, and the groove shall be welded firmly. The number of solder joints shall not be less than the specified requirements, and the diameter of solder joints shall not be less than 1 cm.

Strengthening A514 grade Q steel material steel is the main purpose of adding alloying elements into steel, which can be realized by the following factors: non carbide forming elements and weak carbide forming elements, such as Si, Ni, Mn, etc., dissolve into ferrite to play the role of solid solution strengthening. Ni can improve the toughness of ferrite.

Cold-rolled sheet is mainly used in the manufacturing of household appliances, automobiles, agricultural machinery, etc., as well as the raw material for the base plate of galvanized sheet and tin-plated sheet and thin-wall welded pipe. For stamping grade cold rolled sheet, deep drawing, extra deep drawing and ultra deep drawing grade cold rolled sheet, the steel grades are Q195, Q215, Q235, SPCC, St12, St13, St14. Cold rolled plate: SPCCT-SD, A514 grade Q steel material, SPCC, SPCE, DC01, DC03, DC04, DC05.

The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product A514 grade Q steel material more than 15 years.
