Quenched & Tempered Carbon-Manganese-Silicon Steel Plates for Welded Pressure Vessels by ASTM International

This standard outlines requirements for three carbon-manganese-silicon steel grades, A, B, and C, with Grade C optionally containing boron. The steel plates, quenched and tempered, are designed for welded-layered pressure vessels. The steel must be killed and meet fine austenitic grain size standards. Chemical composition analysis, including carbon, manganese, and other elements, must conform to specified limits. The steel plate undergoes tension testing, meeting tensile strength, yield strength, and elongation requirements.

• Three Grades of Steel: This specification outlines standard requirements for three types of carbon-manganese-silicon steel, labeled Grades A, B, and C
• Grade C Option: Grade C can be produced with an optional boron addition
• Treatment and Use: The steel plates are quenched and tempered, and designed for welded-layered pressure vessels
• Grain Size Requirement: The steel must be killed and meet the fine austenitic grain size requirement
• Composition Analysis: Heat and product analyses are conducted to ensure the material meets the required chemical composition for various elements
• Tension Test: The steel plate undergoes a tension test to confirm it meets tensile requirements such as strength, yield strength, and elongation
