ASTM A193 B7 steel is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low-temperature impact toughness. ASTM A193 B7 steel is suitable for manufacturing large and medium-sized plastic molds and high-strength, high-temperature bolts and nuts that require certain strength and toughness.

ASTM A193 B7 is a high-temperature bolt steel that meets the American standard. This material is widely used in high-temperature and high-pressure occasions, such as chemical equipment, nuclear power plants, and aerospace fields. ASTM A193 B7 is a chromium-molybdenum alloy steel with good corrosion resistance, high-temperature resistance, and oxidation resistance.

The main components of ASTM A193 B7 steel are chromium and molybdenum, of which the molybdenum content is between 0.15% and 0.25% as required by the standard. The tensile strength and yield strength of this steel are very high, reaching 105ksi and 95ksi respectively. In addition, the performance of ASTM A193 B7 steel at high temperatures is also very excellent, and its maximum operating temperature can reach 593°C (1100°F).

In addition to its application in high-temperature and high-pressure environments, ASTM A193 B7 steel is also widely used in the construction industry, where bolts with good high-temperature resistance and corrosion resistance are required. The production process of ASTMA193B7 steel is very strict, requiring the chemical content, processing technology, and heat treatment of the material to meet strict standards. In this way, the quality of ASTMA193B7 steel can be ensured to be stable and meet the standard requirements.

ASTM A193 B7 steel has a wide range of uses. Due to its good high temperature resistance and corrosion resistance, it is widely used in many fields, such as:
