Calculating Sheet Metal Thinning in a Formed Part

By |2018-06-07T19:59:55-04:00Feb 2, 2013|Blog|0 Comments

Through my website, someone from a manufacturing company asked how to calculate thinning in a sheet metal part made from 2mm thick high strength steel. My response: First, I assume the nominal or expected thickness is 2mm. But this is just the aim thickness. The steel mill is allowed to ship product that has some deviation from this gauge – maybe 1.85mm to 2.15mm as an example. So you [...]

Ultra High Strength Steel in 2013 Honda Accord

By |2018-06-07T19:55:37-04:00Jan 31, 2013|Blog|0 Comments

2013 Honda Accord body structure is made of >55% high strength steel with tensile strengths starting at 440MPa. Of this, >17% is ultra high strength steel, with tensile strengths of 780MPa, 980MPa, and a martensitic grade 1500MPa. This 2013 model represents the first use of UHSS in the Accord lineup. In addition, the subframe has steel and aluminum components that are joined via friction stir welding. http://www.honda.com/newsandviews/article.aspx?id=6825-en http://www.autofieldguide.com/articles/honda-accord-the-ninth-generation# -Danny [...]

Steel, Aluminum, and Automotive Market Concentration in China

By |2018-06-07T19:50:43-04:00Jan 28, 2013|Blog|0 Comments

Currently, around half of China’s total steel capacity is owned by the 10 biggest steel firms; the government aims to bring this to 60% by 2015. Also by 2015, targets call for 90% of automobile production and 90% of aluminum production to be done by the 10 largest firms in their respective industries. Furthermore, steel mills will not be permitted to build new capacity in 47 large cities, including [...]

Advanced High Strength Steel (AHSS) for Exposed Applications

By |2018-06-07T19:44:13-04:00Jan 28, 2013|Blog|0 Comments

In one of the first uses of AHSS for automotive skin panels, POSCO is supplying Hyundai with an exposed quality advanced high strength steel with 490 MPa minimum tensile strength. Hyundai was able to reduce the mass of the door by 7%, since this higher strength steel allowed for use of a thinner sheet while maintaining dent resistance. http://www.posco.co.kr/homepage/docs/eng2/jsp/prcenter/news/s91c1010025v.jsp?idx=2103
