12 Heat Treatment Processes:Annealing, Normalizing

(1) For low-carbon steel and low-alloy steel parts with a carbon content of 0.15% to 0.25%, the depth of the carburized layer is usually 0.5 to 2.5mm; (2) After carburizing, it is necessary to perform quenching to obtain martensite on the surface before carburizing intention is completed. 316 Stainless Steel Technical Data Sheet316 Stainless Steel Technical Data Sheet. Types 316 and 316L are molybdenum-bearing austenitic stainless steel which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium nickel austenitic stainless steel such as Type 304. These alloys also offer higher creep, stress-to-rupture and tensile strength

440C Steel - Tool Steel High Speed Steel Tool Steel

Data Sheet - 440C. 440C is a hardenable chromium steel. It has one of the highest attainable hardnesses of the corrosion and heat resisting grades. This grade is magnetic at all times. For those applications where superior machinability is desired and where slightly lower corrosion resistance is satisfactory 440C can be supplied. Beginners Guide on How To Anneal Steel Make It From Its a solid way of making steel take many hours to cool. The ideal cooldown rate for annealing steel is about 70 F per hour, down to about 500 F. In other words, a piece of steel thats cooling from 1500 F to 500 F should ideally take about 14 hours. Actual ideal times will vary by grade of steel, but thats a decent rule of thumb. How to Colour Steel With HEAT :5 Steps (with Pictures The "turning blue" process has nothing to do with hardening of the steel, or its compression. It is caused by a layer of oxide that forms when the steel is heated. The thickness of the oxide is a function of how hot you heat the steel (The color is due to interference of light

S355NL / 1.0546 - SteelNumber - Chemical composition

Go here. Chemical composition % of steel S355NL (1.0546):EN 10025-3-2004. Nominal thickness =< 63 (mm) CEV max = 0.43. For long products the P and S content can be 0.005% higher. For railway application a maximum S content of 0.01% may be agreed at the time of enquiry and order. In sufficient other N-binding elements are present the minimum SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent Tempering:Hold at 200 to 650 °C (400 to 1200 °F) for at least 1/2 hour; air cooling. The temperature and the time at the temperature mainly depend on the required final hardness. Stress Relief:After straightening, forming or processing, the stress of the part can be released at a temperature of 650 to 675 °C (1200 to 1250 °F). UHMW FAQs - Frequently Asked Questions about UHMW UHMW-PE can operate continuously up to 180 degrees F and intermittently at 200 degrees F with custom blends available to enhance the temperature range up to 300 degrees F. UHMW-PE can perform without degradation at extremely low temperatures (-452 degrees F).

WKM DynaCentric High-performance Butterfly Valves

temperatures to -50° F (-46° C) are available in both 316 stainless steel construction and low-temperature carbon steel. Steam Service DynaCentric high-performance butterfly valves also are suited for applications in steam service. Reinforced TFM seats (S02) with high-temperature packing are the standard steam service seal materials. q345a equivalent - ABS ASTM Ship SteelsQ345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa, it has better properties than Q235.According to GB/T 1591 2008, Q345 material has 5 quality grades Q345A, Q345B, Q345C, Q345D and Q345E.
