Cold Work Tool Steel Strip

Main Grades: 75Cr1, 75Ni8, SAE8660
Thickness: 0.08 mm ~ 4.5 mm
Width: 7 mm ~ 650 mm

We guarantee critical quality characteristics for all our products—such as dimensional precision (±0.005mm), surface flatness and straightness (3mm/5m), and consistent mechanical properties—while offering outstanding value, thereby helping customers optimize their development costs.

Q1: Which steel mills do you primarily source your base materials from - domestic or imported?
A1: We primarily use base materials from domestic manufacturers such as Baosteel, Shougang, TISCO, Nanjing Iron & Steel, and Xinyu Iron & Steel. Our imported base materials mainly come from JFE (Japan) and POSCO (South Korea).

Q2: What tolerance precision can you control to?
A2: We operate two Sendzimir 20-high rolling mills from the US, achieving thickness tolerance as tight as ±0.003mm.

Q3: What hardness levels can you provide?
A3: Hardness is customized to customer requirements, up to a maximum of 60 HRC (Rockwell).

Q4: Do you provide chemical composition test reports, and what is the sample delivery lead time?
A4: Every batch is supplied with an MTC (Material Test Certificate) report. Standard order delivery time is approximately 35 days.

Q5: Can you produce according to customer drawings?
A5: Yes, we can produce precision steel strip to custom thickness, width, tolerance, surface finish and hardness requirements, designing the processing route around the customer's intended application to ensure material consistency and stability.

Q6: What certifications does your company hold?
A6: Our quality management system certifications include IATF16949:2016 and ISO14001:2015.
