Piyush Steel is the leading and well-known manufacturer, exporter, and supplier of Stainless Steel 254 SMO Tubes that are built using high-quality material.
About 254 SMO Tubes-
The alloy 254 SMO tubes are basically stainless steel that has a higher content of molybdenum. It got combined with copper and nickel which gives it a blend of decent imperviousness and hole erosion, in situations that contain halide particles such as bromide, chloride, and fluoride arrangements.
S31254 SMO Seamless Tubes is high alloy austenitic steel tubes that are available in different shapes, sizes, custom sizes as per client request. It offers SMO tubes in all forms for wide application usage. The high-quality Tube is thus made using international and national standards.
This product has been selected for some special type of industries like gas and oil, petrochemical industry, and marine.
The high content of molybdenum of tubes lead to improved oxidation rate and the result is a rough surface finish. The tubes possess good weldability and are substantially stronger compared to austenitic grades. It can be easily characterized by impact strength and high ductility. The tubes got established with cost effectual substitute with titanium for additional nickel alloy.

Features-
The 254 SMO stainless steel Tubes exhibit exceptional resistance toward warm seawater and chloride attack. It is best known for outstanding oxidation resistance. Both seamless and welded tubes can withstand high pressure and high mechanical stress. It can even work in corrosive environments and high temperatures. It got formed using solid metal billet drawing over rod piercing so as to create hollow tubes.
SS 254 SMO tubes don’t require any pre-heat and post weld heat conducts. One more quality of it is that it is imperiled so as to hot cracking controllably for weldment. Meanwhile, hardening of the grade is done through thermal treatment. On the other hand, stainless steel SMO structural constancy is collapsed during the soaring temperature beyond 400 Degree C. It needs to be canned after the cold working so as to attain maximum cracking resistance at severe atmosphere.
Other known applications are seawater cooling procedure, sulphuric acid treating plant and oil refinery parts.
We offer stainless steel tubes in a wide range of dimensions, schedules, wall thickness, types, form, end, and length. The length can be double random, cut length, and single random.
Product certification-
The product certification is basically a certifying process that shows the product has passed the performance test as well as various quality assurance test. Thus it meets qualification criteria predetermined in specifications, regulations, and contracts. It got summed up in four steps- application, evaluation, decision, and surveillance.
Prior to certification, the product is supplied to the testing laboratory. Once the product is certified, lab internal procedures with methods listed are collected. The SS test certificates provided are NACE MR 01075, raw material certificates, 3rd party inspection, 100% radiography report, and EN 10204/3.1B.
Material testing-
The material is tested and then certified. It ensure the material undergo strict quality test before it got dispatched to clients. The test that usually got performed are-
• flattening test
• PMI test- positive material identification
• hardness test
• mechanical test
• micro/macro test
• flattening/flaring test
• pitting resistance test
• intergranular corrosion test
Documentation list-
List of documentation is given below-
• material traceability records
• raw material reports
• fumigation certifications
• test certificates certifying
• NABL approved test reports
• MTC as per EN 10204 3.2/ EN 10204 3.1
