Materials Catalog
50+ Material Grades. One Source.
From waterworks-grade A36 plate through API-spec A694 high yield and the nickel alloys that handle sour service and aggressive chemistry, Texas Flange stocks and sources the full material spectrum required by modern piping systems. One distributor, mill-certified inventory, and the documentation your QA team actually wants to see.
The Four Families We Carry
Material selection drives pressure rating, temperature limits, corrosion life, and welding procedure. Every flange and fitting we supply falls into one of four families. Pick the right family first, then narrow to a grade.
Carbon Steel
A105 forged flanges, A350 LF2 and LF3 for low temperature, A516-70 plate, and the full A694 high yield range from F42 through F70 for transmission pipeline service.
Stainless Steel
Austenitic F304/304L and F316/316L are the workhorses. F321 handles elevated temperature where chromium carbide precipitation is a concern. All to ASTM A182.
Alloy Steel
Chrome-moly grades F11, F22, and F91 for elevated temperature creep resistance and hydrogen service. Plus low temperature LF grades when impact testing is required.
Exotic Alloys
Hastelloy C276 and C22, Inconel 625, Monel 400, Incoloy 825, duplex 2205 and super duplex 2507, plus titanium and copper alloys for the jobs nothing else survives.
A Framework For Picking The Right Material
Most material disputes on a project come from skipping one of four questions. Walk through them in order and the spec sheet usually writes itself.
1. What is the design pressure and temperature?
ASME B16.5 pressure-temperature tables drop sharply with temperature. A105 derates fast above 500F. F22 holds rating up around 1000F. A694 high yield earns its Class 600 and above ratings through heat treatment.
2. What is the fluid and how corrosive is it?
Chlorides push you to 316L minimum and often to duplex. Wet sour service triggers NACE MR0175 hardness limits. Hydrofluoric acid alky service is Monel territory.
3. What code governs the system?
ASME B31.3 process piping, B31.1 power, B31.4 liquid pipelines, B31.8 gas transmission, and AWWA for water all impose their own material rules. The code chooses the spec before you do.
4. What is the minimum design metal temperature?
A105 is good to roughly -20F without supplementary impact testing. LF2 takes you to -50F, LF3 to -150F, and austenitic stainless covers cryogenic without a second thought.
Domestic Versus Import
Buy America, Buy American, BAA, and project-specific domestic clauses are not the same rule. We carry both domestic melt-and-manufacture material and import material with full mill test reports, and we keep the documentation trail clean so your inspector can sign off without a second visit.
For a deeper read on the difference between the various domestic content rules, see our reference page on domestic versus import sourcing in the resources library.
