Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium S460QL material carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some S460QL material alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our S460QL material quality. Till now, we keep exporting around 100 tons per month as regularly.
The company sold 50,000 tons of hot rolled plates to Southeast Asian countries, which will help the construction of relevant S460QL material key projects in countries along the “Belt and Road”. In response to the local environment and construction needs in Southeast Asia, the company has made a number of improvements to its export products, with excellent cost performance such as low emissions and low fuel consumption. It is an ideal compaction equipment for the S460QL material construction of high-grade highways, railways, airports, ports and industrial sites. Loved by customers from countries along the “Belt and Road”.
