Material Specification,
Verified by Science.
Every dependable component starts with the right material. Our material specification service pairs precise alloy steel and cast iron grade selection with in-house OES spectrometry, matching each part to the correct international standard. From standard grades to custom alloy formulation, we define, verify, and certify the chemical composition and mechanical properties your application demands.
Material Specification
- Alloy steel grade selection
- Spectroscopic material analysis
- International standard matching
- Custom alloy formulation
Where Composition Becomes Confidence.
A material specification defines exactly what a component is made of and how it must perform: the chemical composition, the mechanical properties, and the international standard it conforms to. Getting this right is the foundation of every reliable part. At Chenab Engineering Works, material specification is not a paperwork exercise. It is a controlled engineering process that begins with grade selection, runs through spectrometric verification of every melt, and ends with a documented material that matches the correct standard for your application. The same discipline underpins the castings we pour and the components we machine and heat treat.
The Right Grade for Every Application
Choosing the correct material grade is the single most important decision in any component's life. Our metallurgists work with your engineering team to specify the optimal alloy steel or cast iron grade, balancing strength, ductility, hardness, wear resistance, machinability, and cost against the demands of the application.
From standard grey and ductile iron through carbon and low alloy steels to stainless and non-ferrous grades, we match the material to the duty, then verify it. Where an off-the-shelf grade will not do, we develop a custom alloy formulation to hit the exact properties required.
- Grey iron and ductile iron grade selection
- Carbon, low alloy, and high alloy steel grades
- Stainless steel and heat resistant grades
- Aluminium, brass, and bronze alloys
- Strength, hardness, and wear targets defined to spec

Spectroscopy That Leaves Nothing to Chance
A specification is only as good as the proof behind it. Our optical emission spectrometry measures the full chemical composition of each melt, element by element, so the material is confirmed against the standard before production continues. Nothing is taken on trust.
Where your part must conform to a foreign or customer standard, we match the grade across international systems and, when needed, develop a custom alloy formulation to meet exact mechanical and chemical targets. Every order can carry a material test certificate.
- OES spectrometry on every heat
- Chemical composition checked to specification
- International standard matching across ASTM, EN, BS, DIN, and JIS
- Custom alloy formulation for special requirements
- Material test certificate supplied on request
Our Material
Specification Process
A controlled five-step route from application review and grade selection through spectrometric analysis, standard matching, and final certification.
Application Review
Understanding the duty, loads, environment, and target properties of the component with your team.
Grade Selection
Specifying the optimal alloy or iron grade, or developing a custom formulation where required.
Spectrometric Analysis
OES verification of chemical composition on the melt, element by element, before pouring.
Standard Matching
Confirming conformance to the applicable ASTM, EN, BS, DIN, or JIS standard and grade.
Certification
Issuing the material test certificate with composition and mechanical property records.
Verified in Our Own Labs
Material specification at Chenab Engineering Works is backed by dedicated in-house laboratories. Our spectrometry, mechanical test, sand, and metallography labs run alongside production, so composition and properties are proven, not estimated.
This integrated testing means a single supplier is accountable for defining, verifying, and certifying your material, from chemical composition through to tensile strength, hardness, and microstructure.
