Heat Treat Temperatures for Hot Rolled Plate Steel: An Overview

Hot rolled plate steel is widely used in various industries, and the heat treat temperatures play a crucial role in determining its properties. When it comes to heat treating hot rolled plate steel, different temperatures can lead to different results.

For annealing, a common heat treatment process, relatively high temperatures are often used. Usually, the temperature can range from around 1300 - 1600°F (704 - 871°C). This high - temperature annealing helps to relieve internal stresses in the steel plate, making it more ductile and easier to work with. In a manufacturing plant, you might hear a worker say, "We need to anneal this hot rolled plate steel at about 1500°F to get it in the right state for further processing."

Quenching is another important heat treatment. In this process, the steel is heated to a high temperature and then rapidly cooled. The heating temperature for quenching hot rolled plate steel typically ranges from 1400 - 1650°F (760 - 900°C). For example, in a steel fabrication workshop, the technician may say, "We'll heat the plate to 1550°F and then quench it to harden the steel."

Tempering usually follows quenching. Tempering temperatures are generally lower, often in the range of 400 - 1200°F (204 - 649°C). This process reduces the brittleness caused by quenching and improves the toughness of the steel. A metallurgist might explain, "After quenching, we temper the steel at around 800°F to get the right balance of hardness and toughness."

Questions and Answers about Heat Treat Temperatures for Hot Rolled Plate Steel

Question: What is the typical annealing temperature range for hot rolled plate steel?Answer: The typical annealing temperature range for hot rolled plate steel is around 1300 - 1600°F (704 - 871°C).

Question: Why is tempering important after quenching hot rolled plate steel?Answer: Tempering is important after quenching hot rolled plate steel because it reduces the brittleness caused by quenching and improves the toughness of the steel.
