JESSOP Type 316 is a molybdenum-bearing austenitic chromium-nickel stainless steel with greatly increased resistance to pitting and crevice corrosion in comparison with AISI Type 304 stainless steel. In addition, Jessop Type 316 offers superior creep, stress-to-rupture and tensile strengths at elevated temperatures. Type 316 is suitable for a wide range of applications in chemical and petroleum processing, power plants, pollution-control equipment, pulp and paper plants and food and pharmaceutical processing. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-488. Producer or source: Jessop Steel Company.

JESSOP TYPE 316L is an extra low carbon variation of Jessop TYPE 316 (See Alloy Digest SS-488, August 1987). It is formulated for resistance to intergranular corrosion in welded or stress relieved structures. JESSOP TYPE 316LM is a more highly alloyed modification of 316L (higher molybdenum and nickel contents) with enhanced pitting and crevice corrosion resistance. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-509. Producer or source: Jessop Steel Company.

JESSOP BX3 is a highly-alloy tool steel designed for service in applications requiring extreme resistance to abrasion. This type of tool steel is the best available for abrasion-resistant properties. It is a high-hardenability (air-hardening), cold-work tool and die steel that can be quenched and tempered to very high hardness (as high as Rockwell C 65). Its many applications include dies of various types, brick mold liners, grinding-wheel molds and wear-resisting parts. This datasheet provides information on composition, physical properties, and hardness. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: TS-378. Producer or source: Jessop Steel Company.

JESSOP JS17Cr-4Ni is a martensitic, precipitation-hardening chromium-nickel-copper stainless steel. It provides an excellent combination of high strength and hardness, short-time low-temperature precipitation hardening and good mechanical properties at temperatures up to 600 F (316 C). Its corrosion resistance is quite good but inferior to lower strength grades produced for corrosion-resistance applications. JS17Cr-4Ni is used widely for critical applications in the aerospace, chemical, food processing and other industries. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-412. Producer or source: Jessop Steel Company.

JS Alloy 255 is a duplex ferritic-austenitic stainless steel. It has been designed to provide a superior combination of high stength and excellent corrosion resistance for a wide variety of applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-495. Producer or source: Jessop Steel Company.

WINDSOR is a medium-alloy, air-hardening tool steel possessing superior abrasion resistance for long service life. Its inherent wearability and toughness make it particularly adaptable for use in dies and punches in extended production runs. It also has excellent nondeforming characteristics. Its many applications include blanking dies, coining, cold shears and punches. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-385. Producer or source: Jessop Steel Company.

Staballoy 734 HS is an austenitic stainless steel with enhanced strength and corrosion resistance and is a stronger version of Staballoy 734 (see Alloy Digest SS-860, August 2002). This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as heat treating. Filing Code: SS-870. Producer or source: Allvac Ltd.
