What is ASTM b117?

The ASTM B-117 salt spray test uses a closed testing chamber in which a salt water (5% NaCl) solution is atomized by means of spray nozzles using pressurized air. The test subject is continuously exposed to the same corrosive atmosphere inside the chamber, then evaluated after removal from the environment.

How do you test for metallurgy?

Metallurgical Testing typically uses microscopy to provide important information about the structure and properties of metal and alloy samples. These services are also called Metallography Evaluation, Metallographic Examination and Metallurgical Analysis.

What are the two forms of steel testing?

What are the tests on steel bars

• Tensile test.
• Compression test.
• Bending test.
• Brinell hardness test.
• Rockwell hardness test.
• Impact test.
• Torsion test.

What are the different types of metal testing?

Subtypes include:

• Bend test.
• Impact test – Further categorised as Charpy test and Izod test.
• Hardness test.
• Tensile test.
• Fatigue test.
• Corrosion resistance test.
• Wear test.

What are the four types of steel?

Authorities grade and categorize steel types into four groups—Carbon, Alloy, Stainless, and Tool.

What is QC in steel?

To specify the various physical and mechanical properties of the finished product, various tests, both destructive and nondestructive, are performed.

What is CASS test?

The Copper Accelerated Acetic Acid Salt Spray (CASS) test method is an aggressive accelerated corrosion test used to determine corrosion resistance of various aluminum alloys and for testing chromium plating on zinc and steel die castings.

What is SST machine?

Salt Spray Test (SST) is a really widespread corrosion method, applied in order to check materials and surface coatings corrosion resistance.

What is NSS in salt spray test?

NSS Testing Method NSS or Neutral salt spray test is a quality assurance test conducted on coated, painted, electroplated, or galvanized material. It is conducted using a standardized salt spray testing machine in which salt water (5% NaCl) solution is atomized by means of spray nozzle using pressurized air.
