Stainless Steel Market Overview

Stainless steel is an alloy of iron containing at least 10% chromium along with other metals like nickel, molybdenum, titanium, copper, etc. Austenitic steel, a family of stainless steel, contains at least 16% chromium, and up to 35% nickel is added as it is highly resistant to rusting and corrosion which makes it suitable for commercial purposes. The price of nickel often impacts the supply-demand dynamics of stainless steel and helps analyze the trends for forecasting. 

According to Beroe's analysis, the net supply of stainless steel is estimated to increase by 5 to 7%, while the net demand is expected to grow by 3 to 5% for the year 2023 compared to the year 2022. Meanwhile, being the net importer the USA stainless steel market holds a size of 2.02 MMT in production growing at 5 to 7% annually from 2021 to 2024 projecting a high level of market maturity.

One of the major constraints faced by the global stainless steel market is the falling levels of nickel inventory resulting in restocking and increased input costs. Also, the implementation of EU Carbon Border Adjustment Mechanism (CBAM) is anticipated to result in higher prices for imported stainless steel.

However, amidst these constraints, the demand for stainless steel in the electric vehicle (EV) sector serves as a major driver which is estimated to reach a 20% increase in 2023. This surge in demand can be attributed to the increasing government support and initiatives in favor of EV adoption as well as the rising popularity of these vehicles among consumers.

With mills requesting orders eight to twelve weeks before rollings and shipments arriving 12 to 16 weeks after the order is placed, stainless sheet purchasers continue to be under-allocated. Project demand is still high, but clients are delaying large stock purchases. Significantly shorter lead times have served as a reminder of the decreased demand as well as the shift in the market environment. While most mills now had material available for delivery in August, lead times have increased to about six months for much of 2020 and 2021. The overall level of end-user demand has remained solid, but several distributors noted decreased offtake from a few clients who have been experiencing shortages of a variety of other components as a result of war-related supply chain disruptions and logistical issues.
