Tool Materials

To select the optimum tool material for the cutting of marine high-strength steels using a hole-opening equipment in the marine environment, this article conducted a comparative study on the corrosion property, tribological behavior and cutting performance of cermet, cemented carbide and coated tools. The results reveal that the coated tool materials have good corrosion resistance with coating protection, and poor wear resistance with adhesive and corrosive wear in artificial seawater, and present moderate cutting performance. In addition, the cemented carbide tool materials show poor corrosion resistance and good wear resistance due to the lubrication effect of corrosion products in artificial seawater, but have bad cutting performance with a high flank wear value. Moreover, the cermet tool materials present acceptable corrosion and wear resistance with adhesive and corrosive wear in artificial seawater and have the excellent cutting performance. Taking into account the corrosion resistance, wear resistance and cutting performance of tool materials and regarding cutting performance as an important indicator, the cermet tool materials with superior comprehensive performances are suitable for the cutting of marine high-strength steels in the marine environment.

Abstract Dogal 600 and 800 DP are high-strength steels with a microstructure that contains ferrite, which is soft and formable, and martensite, which is hard and contributes to the strength of the steel. The designation relates to the lowest tensile strength. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on forming, joining, and surface treatment. Filing Code: CS-160. Producer or source: SSAB Swedish Steel Inc. and SSAB Swedish Steel.

Abstract YS-T 50 to YS-T 140 Steels comprise a series of high-strength, cold-rolled steels designed to meet performance and weight-saving objectives. They are an extension of Youngstown's series of hot-rolled high-strength steels (see Youngstown YS-T Steel, Alloy Digest SA-261, March 1971). The YS-T 50 to YS-T 140 steels have minimum yield strengths ranging from 50,000 psi to 140,000 psi. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and bend strength. It also includes information on heat treating, machining, and joining. Filing Code: SA-331. Producer or source: Youngstown Sheet and Tube Company.

Abstract Bethlehem Lukens Plate (BLP) offers five grades of Spartan high-strength steels with tensile yield strength over 690 MPa (100 ksi). These alloys contain copper for precipitation reactions. They also have improved weldability and toughness compared to ASTM A 514 and A 543 grades. This datasheet provides information on composition, microstructure, hardness, and tensile properties as well as fracture toughness. It also includes information on forming and joining. Filing Code: SA-518. Producer or source: Bethlehem Lukens Plate.
