Production is carried out according to EN-GJS / DIN standards, in grades ranging from EN-GJS-400 to EN-GJS-700, with tensile strength of 400 to 850 N/mm², yield strength of 250 to 600 N/mm², elongation of 3 to 27%, and a microstructure ranging from ferritic to pearlitic, depending on the material grade.
As with grey iron, every batch undergoes:
- chemical composition and microstructure analysis
- mechanical property testing (hardness, tensile strength, yield strength)
- visual inspection and shot blasting of castings
- dimensional inspection against customer drawings with an accuracy of up to ±0.005 mm
The total production capacity of all RS Metal facilities is approximately 12,000 tons of castings per year, with 85% of production exported to markets in the European Union and other countries. The quality system complies with ISO 9001:2015, ISO 14001:2004, and OHSAS 18001:2008 standards.
