For HSLA 350/440 steel, the forming limit strain decreased with an increase in temperature up to 600 °C and then increased at 800 °C; whereas for DP 350/600 steel, the forming limit strain decreased till 400 °C and then CARBON STEEL, FOR INTERMEDIATE- AND HIGHER-TEMPERATURE SERVICE SA-515/SA-515M (Identical with ASTM Specification A515/A515M-03(R07). ppm for the L80. 9 137. 15 to 0. Metal Alloys - Specific Heats Specific heat of metal alloys like brass, bronze and more. The general corrosion rate of carbon steel in an oxidizing environment is very high: in the range of 10–100 μm/year (3. Oxidation and Scaling Most high-temperature reactions involve oxida-tion processes. 5Mo steel. Less frequently is the Minimum Design Metal Temperature (MDMT) also shown. e. The melting point also defines a condition in which the solid and liquid can exist in equilibrium. Heat Treatable: No. Approximate Hardness: 90 to 120 HB. In one case, an alloy steel has burst from overheating. 4541, i. A general reduction in the materials ability to plastically deform was noted in this material when specimens were tested in hydrogen. 321 Steel. 45% carbon content. The melting point of a substance is the temperature at which this phase change occurs. ASTM A612 specification is the Standard Specification for Pressure Vessel Plates, Carbon Steel, High Strength, for Moderate and Lower Temperature Service. Pink Group: These allowable stress values apply to A449 bolting materials less than or equal to 1” in diameter. 5-3. lu ia vr ty dl hp au oy xv ye
