To ensure the same quality of material we are dispatching as required Each piece has undergone a PMI test by the customer. PMI (Positive Materials Identification) is the testing of materials to determine their chemical composition at specific (often multiple) stages of alloy manufacturing or installation.
Ultrasonic testing (UT), is one of a number of non-destructive test methods. based The propagation of ultrasonic wave in the object or material being tested. Most UT applications use very short ultrasonic pulse waves with center frequencies ranging between 0.1-15 MHz and sometimes up to 50 MHz. These are transmitted into materials in order to detect or characterize internal flaws. Ultrasonic thickness measurement is a common example. This allows you to measure the thickness of an object and monitor corrosion.
Impact testing is used to test an object's resistance to high-rate loading. This is often thought of as two objects hitting each other at high relative speeds. The part's or material's resistance to impact is often a determining factor in the life expectancy of a part or the suitability for a specific application. Most impact testing is done using Charpy or IZOD Specimens.
Hardness is the resistance of a sample against material deformation caused by a constant compression load from sharp objects. These tests are based on the basic principle of measuring the critical dimensions left by an indentation created by a specially dimensioned and loaded inserter. We measure hardness using the Vickers, Rockwell, and Brinell scales.
Tensile Test: A sample is placed under controlled tension. failure. These results can be used to choose a material for an application or to control quality. They also help predict how the material will react to other forces. A tensile test can measure properties such as ultimate tensile strength and maximum elongation.
Bend tests deform the test material at the midpoint causing a concave surface or a bend to form without the occurrence of fracture and are typically performed to determine the ductility or resistance to fracture of that material.
Magnetic particle Inspection (MPI), a non-destructive test (NDT), is used to detect surface and subsurface discontinuities in ferrromagnetic materials like iron, nickel and cobalt and some of their allies. This process creates a magnetic field in the part. You can magnetize the piece by either direct or indirect magnetization. Direct magnetization is when an electric current passes through the object. A magnetic field is created in the material. Direct magnetization is when an external source applies a magnetic field to the object but no electric current passes through it. The direction of the electric current, which can be either an alternating current (AC), or a form of direct current(DC) may have magnetic lines of force.
Intergranular corrosion (IGC) testing is the only corrosion test performed as a standardized pre-delivery test. Intergranular corrosion in stainless steels may result from precipitation of carbides, nitrides or intermetallic phases. Only in the most highly oxidizing solutions can intergranular attack be caused by intermetallic phases. When a test is to be restricted to carbides, in a material containing nitrides or intermetallic phases, a less oxidizing solution is chosen. We are performing different IGC test practices as per the ASTM A262 specification.
