ASTM A182 F316L Stainless Steel Cap Forged Threaded Pipe Fitting

ASTM A182 F316L Stainless Steel Cap Forged Threaded Pipe Fitting

Yuhong is a prominent manufacturer, trader, supplier, and exporter in the ASTM A403 WP304 Socket Welded Pipe Fittings industry in China. The stainless steel A182 F316L exhibits a higher chromium content and lower carbon content, resulting in reduced chromium carbide precipitation during welding. With a carbon content as low as 0.03%, this steel is less susceptible to intergranular corrosion and can withstand continuous exposure to temperatures of approximately 1500°F without significant fouling.

It finds suitability in various applications, including automotive headers, machine parts, screws, and food handling equipment. We offer a range of DIN 1.4404 stainless steel butt welded pipe fittings such as tees, reducers, crosses, short elbows, elbows, and end caps. The SS UNS S30400 Butt Welded Pipe Elbow demonstrates excellent forming and welding properties, as well as outstanding oxidation resistance. All our products are developed in a state-of-the-art infrastructure, adhering to international standards to ensure the highest quality.

The ASTM A182 F316L specification covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, valves, and parts for high-temperature service. Following hot forging, specific cooling and heat treatment procedures must be followed, considering factors like austenitization/solution temperature, cooling medium, quenching, etc. The materials must fulfill the required chemical composition criteria for carbon, manganese, phosphorus, silicon, nickel, chromium, molybdenum, columbium, and titanium. Additionally, the mechanical properties such as tensile strength, yield strength, elongation, and Brinell hardness must meet the specified grade requirements. All H and F 63 grades are subject to average grain size testing.

A socket weld is a pipe connection detail where the pipe is inserted into a recessed area of a valve, fitting, or flange. Socket weld fittings are primarily used for Small Bore Piping, typically for pipes with a nominal diameter of NPS 2 or less, as compared to butt weld fittings.

Socket welded joint construction is a preferred choice due to its high leakage integrity and excellent structural strength, although fatigue resistance is lower than butt weld construction due to fillet welds and abrupt mating geometry. Nonetheless, it still offers better fatigue resistance compared to most mechanical joining methods.

Socket weld (SW) fittings are a family of high-pressure fittings extensively used in various industrial processes. They are employed in pipelines that transport flammable, toxic, or valuable materials, ensuring leak-free operation and are suitable for steam systems ranging from 300 to 600 PSI. SW fittings are exclusively designed for use with ASME pipes and share the same size range. They are commonly used in permanent plumbing applications, offering favorable flow characteristics. These fittings are manufactured in compliance with multiple ASTM standards and adhere to ASME B16.11, which specifies pressure-temperature ratings, dimensions, tolerances, markings, and material requirements for wrought carbon and alloy steels. Acceptable material forms include forgings, bars, seamless pipes, and seamless pipes meeting the fitting chemistry, melting practices, and mechanical properties outlined in ASTM A105, A182, or A350. SW fittings are available in three pressure classes: 3000, 6000, and 9000.

Chamfering pipes before welding is unnecessary for socket weld fittings. The alignment does not require temporary spot welding as the fitting ensures correct alignment by design. It is essential to prevent weld metal from penetrating the pipe hole. Socket weld fittings can be used as alternatives to threaded fittings, significantly reducing the risk of leaks. Due to the impracticality of radiography for fillet welds, proper assembly and welding are critical. Fillet welds can be inspected using surface inspection, magnetic particle (MP), or liquid penetrant (PT) inspection methods. Compared to butt-welded joints, socket weld construction offers lower construction costs due to less stringent assembly requirements and the elimination of special machining for butt-weld end preparation.

ASTM A182 F316L Forged Socket Weld Fittings are a low carbon version of 316 stainless steel and are immune to sensitization (grain boundary carbide precipitation). Consequently, they are widely utilized in heavy-duty welded parts measuring around 6mm and above. Typically, there is no discernible price difference between 316 and 316L stainless steel.

ASTM A182 F316L Forged Socket Weld Fittings belong to the standard molybdenum grade, second only to 304 in terms of its significance in austenitic stainless steels. Compared to 304, the presence of molybdenum imparts superior overall corrosion resistance to 316, particularly in chloride environments, exhibiting higher resistance to pitting and crevice corrosion.

Moreover, the austenitic structure of these grades ensures excellent toughness, even at low temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel demonstrates higher creep resistance,Yuhong is a leading manufacturer, trader, supplier, and exporter in the Chinese ASTM A403 WP304 Socket Welded Pipe Fittings industry. Our company specializes in producing high-quality stainless steel A182 F316L fittings, which offer excellent corrosion resistance and welding properties.

The A182 F316L stainless steel has a higher chromium content and lower carbon content compared to other grades. This composition reduces the formation of chromium carbide precipitates during welding, making it less susceptible to intergranular corrosion. It can withstand temperatures up to 1500°F without significant fouling, making it suitable for various applications such as automotive headers, machine parts, screws, and food handling equipment.

At Yuhong, we offer a wide range of DIN 1.4404 stainless steel butt welded pipe fittings, including tees, reducers, crosses, short elbows, elbows, and end caps. These fittings are manufactured with precision and comply with international standards to ensure the highest quality. Our advanced infrastructure and adherence to ASTM A182 F316L specifications guarantee the durability and performance of our products.

The ASTM A182 F316L specification covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, valves, and parts designed for high-temperature service. After hot forging, the fittings undergo specific cooling and heat treatment processes to achieve the desired properties. The materials used meet the required chemical composition standards, including carbon, manganese, phosphorus, silicon, nickel, chromium, molybdenum, columbium, and titanium. Mechanical properties such as tensile strength, yield strength, elongation, and Brinell hardness are also carefully monitored to meet the specified grade requirements.
