The SD Scientific Difference

We are not a general supplier. We are specialists dedicated to solving the most challenging marking and measurement problems in high-temperature manufacturing.

Our flagship product, Iron Hot Marking Chalk, embodies our commitment to quality and focus:

• Engineered, Not Just Manufactured: We utilize proprietary, high-purity refractory materials to create a marker that doesn’t just resist heat—it binds instantly to surfaces up to 2200°F (1200° C).

• Safety & Integrity First: We ensure our products are Sulphur- and Chloride-Free, protecting the integrity of specialty alloys and high-value metals from harmful contamination.

• Real-World Reliability: Our products are rigorously tested in active steel mills and foundries to ensure they stand up to the extreme forces, dust, and constant operation of your environment.

Our Mission

Our mission is simple: To empower industrial professionals with the tools they need to achieve maximum efficiency and accuracy.

We believe that critical marking should be a non-issue. By using the specialized solutions from SD Scientific, your team can eliminate the downtime, material loss, and re-work associated with temporary, vanished, or contaminating marks.
