Steel Casting Cost Factors
According to Emcasting company, there are 5 factors that are affecting steel casting part price
1-Geometry and shape of part
Internal cavities, quantity and thickness of cores, thin walls, long parts, complicated shapes, more than one parting line requirement, non linear parting lines, reverse angles and non symmetrical parts etc. will increase sand casting piece prices.
Mentioned complexities will increase casting defects such as cold lap, core replacement, flash, mismatch, raised core, deformation etc.
2-Alloy and alloying elements
The alloying element(Silicon, manganese, Chromium, Titanium, molybdenum, nickel, niobium and vanadium etc) quantity and tight standards will also increase the prices.
3-Order quantity,yearly volume,
Low volume means higher pieces prices.
4-Required Mechanical properties and heat treatment
Annealing and normalizing are usual heat treatment of steel parts that are used to homogenizing micro structure and decreasing solidification stresses.
In some cases to achieve required properties, multiple and costly heat treatments are used.
5-Requested tests according to safety and critical application
ASTM’s nondestructive testing techniques used to detect and evaluate flaws in materials and objects without destroying the specimen at hand. Such tests include radiographic, ultrasonic, electromagnetic (eddy-current), X-ray, acoustic, and tomographic techniques. These tests are costly and might increase the cost of steel casting part price.
