Case Hardening Engineering Steel - EN32 (080M15)

EN32 (080M15) from Thames Stockholders is a bright drawn engineering steel with low tensile strength and is meant for use in general engineering applications, especially for low stressed components. It is categorized as an unalloyed low carbon engineering steel grade. When case hardened, the material delivers a hard, outer surface with a tough internal core. Tempering of EN32 is suggested to offer maximum case toughness and stress relief with a tempering range from 150–200 °C. A core strength of up to 490 N/mm² can be attained for components when carburized. EN32 should be chosen for any lightly stressed applications where good wear resistance is a requirement. Other engineering steels should be picked when additional strength is required.

EN32 (080M15) can be considered as a ‘crossover’ material as fundamentally it is the same product as EN3B but is marketed and supplied particularly for case hardening work.


EN32 (080M15) profits from being readily machinable and weldable in the supplied condition. As EN32 is a cold drawn material, it is manufactured to much tighter sectional tolerances than mild steel equivalents. Since the material is straighter and flatter, it allows better machining consistency and a more consistent cross section. Thames Stockholders’ EN32 bar product is supplied in a range of incremental sizes which often eliminates the need for customers to have the bar machined down. By delivering EN32 in a form which is closer to the customer’s individual requirements guarantees that time is saved and expenses are curtailed.

Added Cost Savings

Another cost saving factor is the company’s ability to provide customers with EN32 bar stock which is extremely consistent in terms of performance and quality on a repetitive basis. This offers many benefits — for instance, as the company purchases EN32 from prime suppliers, the consistency of the product will mean that customers may not need to alter their machining arrangement because of variances in batches. This level of consistency will certainly have an impact on one’s supply chain and through costs.


EN32 (080M15) is a general engineering steel which is suitable for manufacturing lightly stressed parts and components. Application examples include:

  • Collet chucks
  • Spindles and gears
  • Bushes, cams, and rollers
  • Applications requiring good wear resistance
  • Used in lightly stressed components
