Strip Steel Chemical Composition

Shimfer specializes in producing high precision strip steel and part of that success is owed to the special attention we pay to our strip steel chemical composition. To ensure that customers get material of the highest quality, we use cold rolled stainless steel coils from Posco as raw materials. Posco steel contains higher standard chemical composition than other steel makers in China and their continued supply of raw materials is important to our quality standards. We always strive to maintain product and material improvement so we can meet and exceed our customer’s expectations. It is in this regard that we install a series of quality and chemical compositions checks within our manufacturing process.

The most important quality check in our production process is the strip steel chemical composition testing. This chemical analyses quantifies and qualifies the chemical composition of each material being produced. By knowing the exact chemical composition of the steel in question, we are able to continuously produce end products that satisfy the ISO standards. We have an in-house, highly experienced metallurgist who verifies the quality of strip steel before the final product is released to the customer.

We specializes in producing stainless steel strips in the grade types of 301, 304 and 316 exclusively. Each of the steel grade types has a particular chemical composition as shown by the table below:
