Steel High Strength Low Alloy Plate

The alloying principle of low-alloy high-strength steel mainly uses solid volume strengthening, fine crystal strengthening and precipitation strengthening generated by alloying elements to improve the strength of steel, and uses fine crystal strengthening to reduce the effect of tough-brittle transformation temperature of steel to offset the adverse effect of carbon nitride precipitation strengthening to increase the tough-brittle transformation temperature of steel. The steel can obtain high strength while maintaining good low temperature performance. The performance characteristics of low alloy high strength steel are mainly manifested in the following two aspects.

1. High yield limit with good plasticity and toughness

The most significant feature of low alloy high strength steel is high strength. In the hot rolled or normalizing state, the strength of low-alloy high-strength steel is generally 30% to 50% higher than that of the corresponding carbon engineering structural steel. Therefore, it can withstand large loads. Engineering structures are generally large or large, and the weight of the component itself often becomes an important part of the load, and the strength of structural materials can significantly reduce the weight of the component and further improve its ability to bear other loads. Not only that, this good effect also greatly improves the compactness of engineering components to further improve their reliability, while reducing raw material consumption, reducing costs, and saving resources.

2. Good welding performance and atmospheric corrosion resistance

Welding is the most commonly used method to build engineering structures, so the steel used in engineering structures requires good welding properties. Low-alloy high-strength steel has low carbon content, low alloyed element content, good plasticity, and is not easy to produce quenching structure and cracks in the weld zone, and the addition of Ti, Nb, V, etc., can also inhibit the grain growth in the weld zone, so most of these steels have excellent welding performance, and are generally no longer heat treated after welding.
