Hot-rolled seamless tubes, optionally cold-finished, produced in several steel grades like AISI 4130 (30CrMo), AISI 4140 (42CrMo) and St52.3 (Q345B), delivered simply as-rolled or heat-treated (normalized, quenched and tempered or stress relieved, depending on the usage), manufactured and certified in concordance with the typical international standards and meeting our customer's or our own technical specifications, depending on the required quality and accuracy level for each special need.
As a secondary straightening process, in order to reach higher straightness requirements, semi-automatic or manually controlled hydraulic press straightening machine is applied.
Hollow bars, optionally rough turned, produced in several steel grades like AISI 4140 (42CrMo), AISI 4145H MOD, AISI 4340 (40CrNiMo), starting from hot-rolled round solid bars or from forged round solid bars, delivered typically as quenched and tempered, manufactured and quality controlled as per our customer's or our own technical specifications, including visual inspection, dimensional inspection and ultrasonic testing (UT), as well as the required destructive testing (DT).
- Visual inspection.
- Dimensional inspection.
- Non-destructive testing, like ultrasonic testing (UT) and liquid penetrant inspection (LPI).
- Destructive testing, like chemical composition analysis, tensile test, Charpy V-notch impact test, metallography analysis (grain size and microstructure determination) and hardness testing.
Depending on the required incoterms, we offer sea transportation in the form of full container loading (FCL) or less than container loading (LCL), as well as the insurance for the cargo. We welcome you to quote different options with us, so you can compare and then decide the best one.
