Mechanical Properties:Tested at te mperatures of 25 degrees Centigrade, ASTM A516 grade 70 carbon steel has a density of. 7.7 to 8.03, a Poisson's ratio of 0.27 to 0.30 and an. elastic modulus of A572 Grade 50 steel,A572 gR.50 steel Machining - Steel A572 Grade 50 steel,A572 gR.50 steel Machining. A572 Grade 50 steel specification is for a high-strength, low alloy (HSLA), hot rolled structural steel plate. A low carbon, low alloy steel, these plates have a flat, clean surface. Excellent formability and weldability are characteristic of this grade. A572 can be cut with plasma, oxy-Acetylene, laser, and water jet, as well as with abrasive cut off saws.
A572-50 steel ramps have a carbon content between 0.050.25% that gives excellent formability and is an excellent material for strong and safe welds. A572-50 HSLA steel is versatile and easy to cut. You can cut A572-50 with plasma, oxy-Acetylene, laser, water jet, and abrasive cut-off saws.

Available in four grades:50, 60, 70 and 80 (most popular) and 100. Can be made to three types of chemical requirements:Type 3, Type 7 and Type 8. Suitable at ambient and low temperatures.
Also, the following rules of thumb can be used to determine proper feeds and speeds for drilling ferrous materials. ( NOTE:varying conditions can easily require adjustments ). Feed equals:.001" per revolution for every 1/16" of drill diameter, plus or minus .001" on the total. Speed equals:80 surface feet per minute in 100 Brinell hardness material and the speed should be reduced 10 surface feet per Feeds and Speeds:The Definitive Guide (Updated for 2021)Pitfall #3 No Interpolation of the Manufacturers Data. One of Niagaras rules for adjusting speeds and feeds is when the Axial Depth is between 0.25 to 0.5 Tool Diameters, use 80% of the lowest SFM range. But when Axial Depth is equal to or greater than Tool Diameter use 80% of the highest speed range.
