What is the difference between duplex and super duplex?

Stainless steels are segregated into various classes, mainly due to the distinction in their microstructural phases. While each class has a distinct microstructural phase, stainless steels that belong to the duplex category have a microstructure that is similar to two other classes, i.e. – ferritic and austenitic stainless steel. Duplex stainless steels contain a mixed […]

What is the difference between a2 and a4 stainless steel fasteners?

Difference between a2 and a4 stainless steel fasteners Fasteners in grades A2 and A4, tend to be amongst the most popular ones across global markets. Grade A2, or as commonly known as stainless steel 304 is highly valued for its economical cost and delivering a good performance. Likewise, grade A4, or as known as grade […]

What is the difference between 316 and 316l?

There are several stainless steel grades, which are classified into four major categories. One of the most important categories is austenitic stainless steel. The austenitic stainless steel alloys are further put into several groups based on their chemical composition. One of the most highlighted stainless steel grades belongs to the 300 series. These grades are […]
