► Portable Optical Emission Spectroscopy
⦿ SBCI is focused on improving the on-site testing of our customers by assisting technical staff with many years of experience in the field of chemical analysis. The portable OES can analyze elements at limits as low as 0.03%, for instance can help characterize L-grade (304:, 316L) Aluminium and Vanadium in low alloy steel. Precise analysis and material identification including N, C, P, S, Sn, As & B can also be detected. Currently Fe base, Ni base and Cu base samples can be analyzed with high accuracy.
⦿ SBCI helps to ease customer inconveniences by providing a convenient, reliable and flexible on-site metal analysis for inspection and quality control, instead of having the customer machine samples and send them out. This eliminates days of waiting that could hamper material construction.
⦿ Some of the application industries include Mechanical Engineering, Metal recycling, Power plants, Construction, Petrochemical and more
⦿ The procedure is as per ASTM E135, ASTM E1476 and ASTM E 1916.

► PMI (Positive Metal Identification)
⦿ Positive Material Identification is a well established analytical materials testing and materials identification technique used throughout industrial plant as well as within the metal assembly and component manufacturing industries. It guarantees a material's elemental composition as required for safety compliance and quality control.
⦿ Currently most alloy manufacturers, petroleum refineries, and other businesses responsible for alloy grade verification use technology to quickly and easily separate various grades of stainless steel. The most common, portable, and easy-to-use tool for this purpose is a handheld XRF (x-ray fluorescence) analyzer. These instruments are highly accurate at determining the chemical composition of alloys, and thereby their grade. Moreover, they do so within a matter of 5 seconds or less for most stainless steel grades, without significant sample preparation, and safely.
⦿ Another advantage is that these measurements are non destructive in nature and hence the material composition is not compromised and the customer can go ahead with using the same material.

► Surface Roughness Measurement
⦿ Portable surface roughness measurement measures the surface roughness. The surface topography plays a variety of roles including the coating adhesiveness, corrosion prevention, and fracture resistance.
⦿ Manufacturers need to measure the surface topography to produce consistent and reliable products.

► Coating thickness Measurement
⦿ XRF is a method generally used for material characterization and in special cases can also be used for coating thickness measurement. The coating and the substrate both produce X-ray fluorescence radiation, but the coating attenuates the substrate’s radiation. The degree to which this attenuation takes place can help determine the thickness of the coat. There are general difficulties in this method due to interference of the signals, but our lab can overcome this difficulty having understood the cause, by using high resolution detectors.
⦿ FTypical industries are: Electronics, Jewellery, coatings, platings, manufacturing
⦿ The procedure is as per ASTM B568

► In-Situ metallography
⦿ In-situ metallography is a useful tool for non destructive testing of materials and studying the phase composition of the metal that has failed or is being used for an application.
⦿ Damage mechanisms like creep, fatigue, stress relaxation, improper case hardening, manufacturing defects, intergranular corrosion, hydrogen attack can all be quickly analyzed and preventive action be taken before serious damage can occur.
⦿ SBCI has vast experience in conducting metallographic studies and also failure analysis to quickly report any case of material deviation and early case of material discrepancy.
