Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality ASTM B444 Seamless Pipe, 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.
Scope And Manufacturing
ASTM B444 specification covers UNS N06625 and UNS N06852 nickel-chromium-molybdenum-columbium alloys and UNS N06219 nickel-chromium-molybdenum-silicon alloy in the form of cold-worked seamless pipe and tube. UNS N06625 products are furnished in annealed Grade 1 and solution annealed Grade 2 while UNS N06219 and UNS N06852 are in solution annealed condition only. Chemical testing shall be performed on each type of material and shall conform to the chemical composition limits specified for carbon, manganese, silicon, phosphorus, sulfur, chromium, tantalum, columbium, cobalt, molybdenum, iron, aluminum, titanium, copper, and nickel.
The material shall undergo tensile testing and shall conform to the required room temperature tensile properties like tensile strength, yield strength, and elongation depending on the heat treatment used and including small diameter and light-walled tubing. Each pipe or tube shall undergo hydrostatic testing and shall conform to the allowable fiber stress and also be examined with a nondestructive electric test as prescribed.
