C40 Introduction

Generally, the high carbon steels contain from 0.60 to 1.00% C with manganese contents ranging from 0.30 to 0.90%. The pearlite has a very fine structure, which makes the steel very hard. Unfortunately this also makes the steel quite brittle and much less ductile than mild steel. 
C40 Stainless Steel Usage
Mainly used in the manufacture of petroleum, chemical, gas separation and shipping container or other similar devices, such as all kinds of tower vessels, heat exchangers, 
torage tank and tank car, etc.
