Leading manufacturers and suppliers of 1.4571 Stainless Steel Seamless Hydraulic & Instrumentation Tubes (A), engineered for corrosive and high-temperature applications. The titanium-stabilized EN 1.4571 grade resists intergranular corrosion and maintains strength after welding.
Our 1.4571 Stainless Steel Seamless Hydraulic & Instrumentation Tubes,
also known as AISI 316Ti, are engineered for corrosive and
high-temperature environments where long-term structural stability, weld integrity,
and reliable performance are essential. The titanium-stabilized composition of
EN 1.4571 (X6CrNiMoTi17-12-2) prevents carbide precipitation in welded
and heat-affected zones, significantly reducing the risk of intergranular corrosion
during continuous thermal exposure and cyclic operating conditions.
The seamless, cold-finished construction ensures uniform wall thickness and
exceptionally smooth internal surfaces, minimizing pressure losses and maintaining
consistent, contamination-free flow in critical hydraulic and instrumentation
systems. The added molybdenum content enhances resistance to pitting, crevice
corrosion, and chloride-induced stress corrosion cracking in aggressive chemical
and marine environments.
Widely used in chemical processing plants, refineries, power generation facilities,
offshore and marine systems, and high-reliability industrial automation, our
1.4571 stainless steel seamless tubes are manufactured and tested to international
standards to deliver a durable, high-performance, and cost-effective solution for
corrosive, heat-intensive, and safety-critical service applications.
Produced using advanced cold drawing and seamless forming processes to achieve uniform wall thickness, tight dimensional tolerances, and smooth internal surfaces for reliable fluid transfer and accurate instrumentation performance.
The titanium-stabilized chemistry of 1.4571 / AISI 316Ti prevents carbide precipitation in welded and heat-affected zones, significantly reducing the risk of intergranular corrosion during high-temperature service and thermal cycling.
The added molybdenum content provides excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking in aggressive chemical, marine, and offshore environments.
Precision-finished internal surfaces reduce friction, minimize pressure drop, and promote stable, contamination-free flow in sensitive measurement and process control systems.
Maintains mechanical strength and corrosion resistance under continuous heat exposure, thermal cycling, and oxidizing service conditions common in industrial and process plant applications.
Engineered for extended durability, reduced downtime, and lower lifecycle costs in chemical processing, refineries, power generation, offshore installations, and high-reliability industrial automation systems.
1.4571 Stainless Steel Seamless Hydraulic & Instrumentation Tubes are manufactured using precision cold drawing and cold rolling processes, followed by controlled solution annealing and pickling or bright annealing. This produces a fully austenitic, homogeneous microstructure with excellent surface quality, strong weld-zone stability, and enhanced corrosion and heat resistance for demanding hydraulic and instrumentation service environments.
Each tube undergoes comprehensive quality control including Eddy Current Testing (ECT), Hydrostatic or Pneumatic Pressure Testing, Positive Material Identification (PMI), chemical composition verification, mechanical and elevated-temperature testing, dimensional inspection, and 100% visual examination. These procedures ensure full compliance with ASTM A213 / A269 and ASME SA213 / SA269 standards for safe and reliable performance in corrosive, high-temperature, and safety-critical instrumentation environments.
Manufactured in accordance with ASTM A213, ASTM A269, ASME SA213, ASME SA269, EN 10216-5, DIN EN 10088-2, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU directives. Tubes are supplied with EN 10204 3.1 / 3.2 Mill Test Certificates (MTC), ensuring full traceability, regulatory compliance, and acceptance for EPC, chemical processing, refinery, power generation, offshore, and industrial automation projects worldwide.
