Chemical composition

AS14 automotive high grade machinability steel is produced in CIS countries according to GOST 1414 and TU -14-1 - 878 standards. This steel belongs to the group of sulfur-manganese steels, which contain high amount of lead, as it follows from the table:

Element Carbon Silicon Manganese Chrome, nickel, copper Sulfur Lead
Content, % 0,10...0,17 Up to 0.12 1,00...1,30 Up to 0.25 0,15...0,30 0,15...0,30

The amount of phosphorus in AS14 steel is allowed to be no more than 0.1%.

The foreign counterparts of this steel are grades 11SMnPb30 and 1.0718. These steels have some chemical composition different from AC14, which is demonstrated in the table below:

Element Carbon Carbon, silicon Carbon, silicon Sulfur Lead Phosphorus
Content, % Up to 0,14 Up to 0.05 0,90...1,30 0,27...0,33 0,20...0,35 Up to 0,11

Properties and application

These steels can be delivered annealed and annealed, calibrated or with special surface finish (GOST 14955). They are used in machining processes on automatic machines. Typical parts - piston rings, brake cylinder blocks and other parts like bodies of rotation, with complex inner contour.

Physical and mechanical properties:

  • Tensile strength, MPa - 410...490 (lower values correspond to annealed steels);
  • yield strength, MPa - 380...390;
  • Relative elongation, % - 20;
  • Relative narrowing, % - 10...12;
  • Brinell hardness, NV - not more than 235.
