Products Description
1.4002 1.4919 Welded Pipe
Characteristics of stainless steel welded pipes:
First, small-diameter stainless steel welded pipes are produced continuously online. The thicker the wall thickness, the greater the investment in the unit and welding equipment, and the less economical and practical it is. The thinner the wall thickness, its input-output ratio will decrease accordingly; secondly, the process of the product determines its advantages and disadvantages. Generally, welded steel pipes have high precision, uniform wall thickness, and high brightness inside and outside the pipe (steel pipes are determined by the surface grade of the steel plate) Surface brightness), can be arbitrarily fixed length. Therefore, it reflects its economy and aesthetics in high-precision, medium and low-pressure fluid applications.

1.4002 stainless steel is a corrosion-resistant alloy containing 12% chromium, 85% iron, and 1% each of manganese and silicon. It has a high tensile strength and is commonly used in annealing, especially metal fabrications that are difficult to anneal after welding.Although oxyacetylene welding is not recommended for stainless steel type 405, it can be welded using shielded fusion or resistance techniques. Electrodes that contain columbium are used in preference to aluminum to control hardening.Before annealing, 405 stainless steel is soaked at 649-760°C (1200-1400°F) followed by air-cooling. The temperature of the steel can then be increased to 1038-1121°C (1900-2050°F).
1.4919 stainless steel has higher strength at elevated temperatures and is used for structural and pressure vessel applications at temperatures above 932°F (500°C). The higher carbon content of 316H also delivers higher tensile and yield strength than 316/316L and its austenitic structure provides excellent toughness down to cryogenic temperatures.
