What is ASTM A48 Class 35b?

Cast iron ASTM A48 class 35 is equal to HT250, FC250, GG25, G25, FGL250, T260, O125, which is a type of high grade gray cast iron. As for this grade of iron, the tensile strength of test bar should be min. 250 MPa, the hardness should be 190-240 HB.

What is ASTM A48?

ASTM A48 Class 30 (Related Standards – DIN GG20, BS 1452 Grade 220) is a gray cast iron. Gray iron consists of graphite flakes in a metallic matrix. The low cost of production and attractive properties make gray iron one of the most commonly used ferrous alloys.

What is ASTM a276?

This specification covers hot-finished or cold-finished bars except bars for reforging. It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels.

What is ASTM A351?

The ASTM A351 specification covers austenitic steel castings for valves, flanges, fittings, and other pressure-containing parts. The steel shall be made by the electric furnace process with or without separate refining such as argon-oxygen decarburization.

What is the grade of carbon steel?

Carbon Steel has three main subgroups depending on how much carbon is in the metal: Low Carbon Steels/Mild Steels (up to 0.3% carbon), Medium Carbon Steels (0.3–0.6% carbon), and High Carbon Steels (more than 0.6% carbon).
