Comparison of stainless steel 304 and 304L: The main difference between 304L and 304 is the carbon content. The carbon content of 304 is less than or equal to 0.08, and the carbon content of 304L is 0.03 max. Secondly, sa675 grade 70, 304 stainless steel is a versatile stainless steel, which is widely used in making equipment and parts that require good comprehensive performance (corrosion resistance and formability), and 304L is a variant of 304 stainless steel with a low carbon content, which is used for Welding occasions.

Processing performance of quenched and tempered steel: sa675 grade 70 plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.

Mechanical Properties A242 steel:
ASTM A242 specification is made for low alloy steel with high strength, it has good atmospheric corrosion resistance, some applications has shown that it has better corrosion resistance than ASTM A36 steel and ASTM A572 Grade 50.
Tensile: 70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4)
Yield: 50 ksi min (3/4 and under), 46 ksi min (3/4-1.5) 42 ksi min (over 1.5-4)
Elongation: 16% min in 8” 19% min in 2” (for plates wider than 24”)
