From Strength to Corrosion Resistance: Key Elements in Pressure Vessel Material Selection

Core material selection criteria:
Mechanical properties: the material needs to meet the design strength requirements, can withstand the working pressure and structural stresses
Corrosion resistance: need to adapt to the characteristics of the medium and environmental conditions, to ensure that the service life
Economy: comprehensive assessment of material costs, processing costs and maintenance expenditures
Craftsmanship: good processing and molding capabilities (welding / bending, etc.), to facilitate the installation of internal components
Availability: Material specifications should be in line with industry standards to ensure supply stability.
Comparison of common material properties:
Stainless Steel (MTSCO core product)
▫ Material Coverage: 304/304L, 316/316L, 31803 and other austenitic/duplex steels
▫ Advantage: Chromium forms a passivation film, excellent chemical corrosion resistance
▫ Characteristics: good ductility, easy processing and molding, low maintenance costs
▫ Applications: food/chemical containers
Nickel Alloys (MTSCO area of specialization)
▫ Models available: Monel 400, Alloy 625, Alloy 825, etc.
▫Strengths: Outstanding performance in extreme conditions (high temperature/corrosion)
▫ Characteristics: high crack resistance, service life of more than 20 years
▫ Application: petrochemical/nuclear core equipment
Carbon Steel
▫ Strengths: low cost, high strength (thinnest wall thickness), impact resistance
▫ Limitations: poor corrosion resistance, difficult to mold
▫ Applications: conventional pressure vessels
Lightweight Metals
Aluminum: high strength and light weight, suitable for laboratory vessels (non-high pressure)
Titanium: biocompatible, excellent thermal conductivity, suitable for medical/heat exchange equipment
