Carbon structural steel refers to the kind of steel which is mainly used in construction and engineering structures without adding alloy elements. Among all kinds of steel, S690QL plate equivalent, carbon structural steel has a large output, the most extensive use and low price. Carbon structural steel is often rolled into various steel bars (round steel, square steel, flat steel, hexagonal angle steel, etc.), section steel (I-beam, angle steel, channel steel, L-shaped steel, etc.), profiled steel and steel plate. Carbon structural steel is mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Generally, heat treatment is not required for carbon structural steel.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel S690QL plate equivalent is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of S690QL plate equivalent etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

The yield strength of S690QL plate equivalent, Q235 steel plate decreases with the increase of thickness. Q235 steel plate thickness≤16mm, yield strength is 235MPA; 16mm < Q235 steel plate thickness≤40mm, yield strength is 225MPA; 40mm < Q235 steel plate thickness≤60mm, yield strength is 215MPA; 60mm < Q235 steel plate thickness≤100mm, yield strength is 205MPA; 100mm < Q235 steel plate thickness≤150mm, yield strength is 195MPA; 150mm < Q235 steel plate thickness≤200mm, yield strength is 185MPA.

Expect in the S690QL plate equivalent goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen S690QL plate equivalent product development technology, excellent production team, hand strict quality control, sales and after-sales service.
