NXF UNS S30400 ASTM 304/JIS 304/EN 1.4301 DN6-1200 Class3000-9000 Stainless Steel 304 Forged Fitting 90 Deg Threaded Elbow
Stainless Steel 304 Introduction
commonly referred to as "18/8" because of its nominal composition of 18% chromium and 8% nickel, with the balance being iron plus small amounts of carbon, manganese, and silicon. It offers an excellent balance of corrosion resistance, formability, and weldability, making it the default choice for general-purpose applications. In its annealed condition, it is essentially non-magnetic and maintains good toughness across a wide temperature range, including cryogenic service.
Typical uses include kitchen equipment, food and beverage processing, architectural panels, chemical containers, water piping, automotive trim, and fasteners. It performs well in atmospheric, fresh-water, and mildly chemical environments.
Its main limitation is susceptibility to chloride-induced pitting and crevice corrosion, so it is not recommended for marine,
coastal, or high-salt service — for those environments.
Threaded Elbow Introduction
1. Product Overview
Threaded elbow is an essential pipe fitting used to change fluid flow direction in piping systems. Equipped with internal and external threads, it enables quick, welding-free pipeline connection and steering, featuring simple installation and strong practicability.
2. Standard & Specification
It is offered in mainstream 90° and 45° angles to adapt to diverse pipeline layouts. Multiple thread standards such as NPT, BSP and BSPT are available, with complete size ranges covering most medium and small-diameter pipeline applications.
3. High-Quality Material
Manufactured from premium carbon steel, stainless steel and malleable cast iron, the elbow owns stable mechanical properties, good hardness and toughness. It resists deformation and cracking, adapting to long-term stable service in various piping environments.
4. Structural & Performance Advantages
Adopting precision thread processing and integral forming technology, the product has smooth thread teeth for tight, leak-proof connection. The optimized inner flow channel reduces fluid resistance, ensuring efficient and stable fluid transmission with excellent pressure resistance and corrosion resistance.
5. Application & Quality Assurance
Widely applied in petroleum, chemical, water supply and drainage, mechanical equipment and plumbing engineering, it is ideal for narrow spaces and frequently disassembled pipelines. All products pass strict dimension, thread and pressure tests, complying with international standards for reliable pipeline operation.

Threaded Elbow Produce Processing
1. Raw Material Inspection
We select qualified carbon steel, stainless steel and malleable iron raw materials. Strict chemical composition and mechanical property tests are conducted to ensure all materials meet international standards before formal production.
2. Cutting and Shaping
According to product specifications, raw materials are precisely cut and bent through professional equipment. The preliminary elbow shape is formed to ensure consistent wall thickness and regular outline of each fitting.
3. Integral Forging and Forming
The semi-finished products undergo high-temperature forging and integral forming. This process eliminates internal pores and defects, improves material density, and enhances overall structural strength and pressure resistance.
4. Precision Thread Machining
Professional thread lathes are used for internal and external thread processing. Strictly following NPT, BSP and BSPT standards, the threads are smooth, uniform and precise to ensure tight connection and no leakage during assembly.
5. Surface Treatment
The finished elbows are processed by polishing, pickling, galvanizing or anti-rust treatment. It effectively removes surface oxide and burrs, improving corrosion resistance, oxidation resistance and appearance quality.
6. Strict Testing and Packaging
All products pass dimensional inspection, thread detection and hydraulic pressure testing. After confirming no defects and meeting standards, qualified products are marked and professionally packaged for safe transportation and delivery.
