Introduction

WDML-100 slow strain rate stress corrosion testing machine is mainly used to test and study the mechanical properties of metal materials, metal products, etc. under static tensile stress, simulated corrosion conditions, temperature, force, etc., and measure their thermal deformation characteristics. The equipment fully meets the GB/T 15970.7-2017 Corrosion Stress Corrosion Testing of Metals and Alloys Part 7: Slow Strain Rate Test standard. It can achieve constant displacement rate loading, constant load loading, and holding load loading tests.
