ASTM B444 Seamless Tube Manufacturers In India

Sachiya Steel International is a well-known firm in supplying and trading ASTM B444 Seamless Tube, which has excellent resistance to localized corrosion including inter – granular, pitting and crevice corrosion. However, surface finish of ASTM B444 Nickel-Chromium-Molybdenum-Columbium Pipes formed is much better than that observed with austenitic stainless steels.

The high strength, low Sulphur limits, and the dual metallurgical phase in ASTM B444 Nickel-Chromium-Molybdenum-Columbium Tubes increase energy required to cut and increase in tool wear. Chips in ASTM B444 Nickel-Chromium-Molybdenum-Silicon Pipes tend to be long and stringy as the lack of Sulphur prevents chip breaking. Much like SS 304L and SS 316, chip management in ASTM B444 Nickel-Chromium-Molybdenum-Silicon Tubes is important.

Care must be taken when assigning cutting conditions to ASTM B444 Nickel-Chromium-Molybdenum-Silicon Alloy Pipes and is more difficult than for machining austenitic stainless steels. It will be necessary to lower cutting speed in ASTM B444 Nickel-Chromium-Molybdenum-Silicon Alloy Tubes, where these cutting speeds are about 30 % lower than Grade 316L. However, it is important not to lower the speed too much of ASTM B444 Nickel-Chromium-Molybdenum-Columbium Alloy Pipes as cutting temperatures must be high enough at the tool tip to keep cutting forces low.

ASTM B444 Nickel-Chromium-Molybdenum-Columbium Alloy Pipes has a high work hardening rate, and efficient machining requires rigid and overpowered machines, sharp tools, preferably carbide – tipped, and heavy, constant feeds. Sachiya Steel International is a well-known firm in supplying and trading ASTM B444 Tubes, where pitting corrosion is the most prevalent form of corrosion in stainless steels.
