Difference between ASTM A213 and A269 Stainless steel tubing

What are the main differences between the ASTM A213 and A269 Stainless Steel Tubing Standards, other than their stated uses in the standard? Is one better than the other for general service Type 304 instrumentation tubing?

Also why is the finish on some tubing conforming to these standards dull while another source might have a polished surface?

 

A-213 pertains to seamless ferritic and austenitic alloy tubing of minimum wall thickness. Some of the ferritic compositions within the spec are not truly stainless. A-269 is seamless and welded austenitic stainless steel without specifying minimum wall. In 304 there are some minor composition differences, but these are generally not consequential. Most 304 on the market will meet either composition spec. The difference between the bright and dull finish depends on whether the producer finished by bright annealing or by pickling. A-269 is more commonly used for specifying instrumentation tubing. I suggest specifying passivated tubing, and if to be installed by welding, be aware of the significant effect of sulfur level on weld penetration and the difficulty of welding two pieces with very different sulfur contents.

 

Similarities Between Grade Astm A213 And Astm A269

The ASTM / ASME Standards Follow The Similar Steps In Manufacturing Process Of Astm A213 And Astm A269 Products And Also Both The Materials Used To Resist The Oxidations And Corrosion To Make The Applications Efficient In The Elevated Temperature. The Tensile Strength And Stress-Corrosion Cracking After The Post Manufacturing Process Are Excellent In Both ASTM Grades.

 

Difference Between Astm A213 Vs Astm A269 Grade

Astm A213 Material Standard Specifications Covers The Seamless Ferritic & Austenitic Steel Boiler, Super Heaters And Heat Exchanger Tubes. The Process Of Manufacturing These Tubes Are Seamless Process And Also Designed In Hot Finished & Cold Finished As Preferred For The Customer’s Application Demands. And Austenitic Stainless Steel Tubes With Astm A213 Grades Fabricated In The Heat Treated Conditions To Make It Perfect & Well Performed For The Elevated Temperatures. It Defines In The Minimum Wall Thickness.

Astm A269 Material Standard Specifications Covers Nominal Wall Thickness And Welded Austenitic Steel Tubing. It Is Usually Used For General Corrosion Resistances And Performing Well For The Low & High Temperatures To Successfully Completion Of The Applications. The Furnishing Process Of The Done In The Heat Treated Conditions To Ensures The Process, And For A Well Going Way Experts Keep On The Eye On Each Of The Step Of Manufacturing. It Does Not Define In The Minimum Wall Thickness.

 

Astm A213 And Astm A269 Testing Factors:

The Testing Process Of The Both Materials Have To Pass The Similar Steps To Ensures That It Is Perfect For The Industry Use Now. The Test Performed By The Industry Experts Are Tension Test, Flaring Test, Flange Test, Reverse Flattering Test And Hardness Test To Make Sure That All The Factors Of The Materials Are Follow The ASTM / ASME Standards And Ready To Use In The Big Industry Machineries. Also Both Materials Passes The Non-Destructive Electric And Hydrostatic Test For Making Them More Compatible In Complex Situations.

There Are Lots Of More Chemical Makeup And Fabrication Processes Similarities In Both The Materials And This Will Sometimes Creates Confusion To Choose The Right One.

Know The Difference Before You Purchase Astm A213 And Astm A269 Materials

After Knowing The Differences You Can Differ Both The Products And Can Easily Choose For Your Needs From Both Of Them. You Can Understand The Differences Of The Materials On The Behalf Of The Specifications, We Have Mentioned In Above Section.

But We Know, For This Process Of Selection Needs The Good Knowledge About These Materials Or Need Experts To Make The Perfect Decisions. So, To Help You In This Solitaire Overseas Experts Will Be There For You To Help You To Choose From Astm A213 And Astm A269 And Also Provide You The Best High Quality Materials As Per Your Demands.
