Grade 304L Stainless Steel Coils/Strips
What Are Stainless Steel Strips Grades?
Common use stainless steel strips grades are often represented by
digital symbols.
There are 200 series, 300 series, and 400 series.
They are expressed in the United States, such as 201, 202, 304,
316, 410, 420, 430, etc.
Chinese stainless steel grades are It is indicated by element
symbols plus numbers, such as 1Cr18Ni9Ti, 0Cr18Ni9, 00Cr19Ni10,
1Cr17, 3Cr13, 1Cr17Ni7, etc.
The numbers indicate the corresponding element content.
The stainless steel strips can be divided into normal austenitic
grade, ferritic grade, martensitic grade, duplex grade,
precipitation hardening grade and super austenitic grade.
304(1.4301)/304L(1.4307)/304H(1.4948) STAINLESS STEEL
Stainless Steel Grade 304 is the standard 18/8 (18% chrome, 8% nickel) austenitic stainless
steel. It is a non-magnetic alloy in the annealed condition,
however, becomes magnetic as it is cold worked. It is the most
ordinarily utilized of all stainless grades. T304 can be
effortlessly welded and is the preferred for many deep drawn, spun
or formed parts due to its high ductility.
Stainless Steel Grade 304L has oxidation resistance to a maximum temperature of 1650°F
(899°C) continuous without considerable scaling. The maximum
temperature for intermittent presentation is 1500°F (816°C). Since
304L is an additional low-carbon variety of 304 it can frequently
be utilized in the “as-welded” condition (without annealing), even
in severe corrosive conditions, except for applications indicating
stress relief. 304L has good welding qualities and can be welded by
all standard strategy; however, consideration should be paid to
maintain a strategic distance from weld “hot cracking”. To relieve
stress during severe forming or spinning welding may be followed by
annealing.
Stainless Steel Grade 304H includes a high carbon content making the steel more suitable for
utilization in applications where high temperatures are available.
The benefit of this grade is that it is an austenitic
chromium-nickel steel alloy as well as the greater carbon content
distribute to increased tensile and yield strength. The material is
recommended for utilizing in ASME pressure vessels in working
service above 525° C because of the grade's heat resistant
properties.

Company Profile
TISCO STEEL, known as a famous and largest stainless steel
manufacturer in CHINA, was founded in the year of 1934, and the
headquarters in Shanxi province.
TISCO STEEL has been focusing on developing stainless steel and
other special steels for a long time. With the development of the
enterprise, we set up a branch in Jiangsu Province called Jiangsu
