Stressproof®
A specialty steel product produced with an innovative process
Stressproof® is produced using a proprietary process that draws the bar through a special die under heavy draft, then stress relieves it in a precisely controlled furnace. Niagara LaSalle developed this groundbreaking process in 1938 and forever changed the economics of production. In this modern age, uniformity in the machinability of a product is a crucial factor in improved productivity.
Stressproof® is electro-magnetically tested using eddy currents. Although it also can be induction hardened, it should be monitored for quench cracks. Niagara LaSalle is exceptionally responsive to the needs of our customers and puts a high priority on providing uniformity in the machinability of our products in order to improve productivity.
Our exclusive Stressproof® products not only meet the minimum properties of ASTM A311 but also have controlled low stresses, reliable machining, and improved surface quality.
